I... don't know about the megastar question... Hmmm.

It could be possible that Yinu is a megastar, but I honestly don't see Papa being okay with that, like at all. I feel like the only reason Mama let Yinu become a megastar was so that Yinu had something to think of other than Papa's death.

But that makes me wonder then how Neon J would have gotten into contact with the Spinose family. At first I was thinking about him meeting them through NSR, but that wouldn't be happening in this version because Neon HAS to meet Papa before he dies, and Yinu only joins NSR after Papa dies.

So I would say that Neon met Papa through chance. Neon was visiting the cybernetic hospital either for a checkup or to talk with doctors/mechanics. And Papa was at that specific hospital to at least think about the possibility of getting a cybernetic heart.

The doctors would introduce Neon to Papa, they talk for a bit, exchange contacts and talk some more as Neon truly wants to help him and Papa is now a bit more open to the idea of cybernetics.

So anyway, once all that happens and Papa is alive and Neon ends up being a family friend. I would say that Neon offers Papa, Mama, AND Yinu a spot to try out at the Lights Up auditions. Yinu is super excited and just wants to play piano with Papa while Mama is on harp.

I can see Papa again being hesitant, but knowing that Neon works for NSR would ease his anxiety. They end up playing a double piano duet with harp accompaniment that has EDM elements as Neon suggested that would give them a better chance (with him teaching the family how to do EDM. I can see OG Yinu getting in without any EDM in her audition because her age made her a great candidate/special case, but with Papa and Mama accompanying her here they NEEDED that EDM to help them get picked).

So, that was all just a long winded way to say that I see Papa, Mama, and Yinu being the charters for Natura together. Obviously Mama and Papa do all the paperwork and remixing, but Yinu ends up being the main face of the trio as she is so young and brilliant. Sometimes she will even do solo shows which actually gets more fans and more power output because of her passion and confidence playing alone (so yes, Yinu is also better at powering the Qwaza alone than when she is with her parents lol).

Anyway, back to the other questions. Papa probably would have SOME affects still, but they would all be psychological and not physical. Think something like phantom pain. He will be physically all right but sometimes he feels like he is about to collapse. This would be what brings him and Neon very close I think, as Neon knows all too well what Papa is going through (well not EXACTLY because Neon still has his own heart, but one of his lungs is gone so he kinda knows what it's like to have an important internal organ fully removed and replaced).

That flower crown idea is so cute! Of course Papa would do that! He would be the best at it too. Neon would probably get a flower necklace since it would fall off his screen too easily, but it would still be super pretty. Also imagine flower arm bracelets for Yinu, flower rings for DJSS, and then flower crown or a flower veil for Mama. Papa is way too skilled at flower crowns and nothing will be able to stop him.

And hmmm, space dates... I don't know really. Yinu would definitely not be allowed to go as she is too young and it would be dangerous. Also it would cost a LOT of money to do so and need a LOT of preparation. I don't see them going on many space dates. At least not in actual space.

I would like to believe there is a way (either with science magic/passion or elemental magic) that allows people to experience zero-G while not going directly into space. I say this because Papa and Neon would probably be disqualified from ever going into space because of their cybernetics (even if it has been a while since cybernetics have been around, it still hasn't been tested of how cybernetics would react in space. At least major cybernetics relating to internal organs).

So definitely there would be dates to Astronomi (what I THINK is the equivalence of NASA based on the logo) where they are just touring. And then there would be a date in the zero-G device thingy after Neon and DJ talk to people.

I would say their time would be very limited, at least Papa's and Neon's. Mama and DJSS would be able to stay in longer as they are cybernetic free, and they probably would as Papa and Neon tell them to have fun while they talk outside the chamber. They do have fun though together when they can. I can see the four dancing, Mama and DJSS dancing in zero-G and talking while Neon and Papa slow dance as Neon sings and Papa hums. Kinda like parallel playing but more like parallel dating lol.

But yeah, this would be a very fun experience and DJSS gets to show off all he knows and even talks to some people he knows there and introduce them to their significant others. All good times (now Neon taking them on boat rides/battleship tours is a whole other thing lol)
