If they HAD somehow managed to find Bonnie in his busted up state and repair him, long after Monty took over the bass
I don't really think it'd be a fight for who is gonna be the bass player now
I imagine one of 3 scenarios happening
1. Bonnie sees how well Monty is doing on base and how much the kids love him and decides its a perfect chance for him to just take it easy only running the bowling alley after everything he's been through
2. Monty doesn't really WANT to be the bass player and is more than happy to go back to merely running gator golf (hence him canonically in game ditching shows to stalk the catwalks above gator golf)
3. The most fun but unlikely option, Monty is already far more popular of a bass player than Bonnie was so management won't put Bonnie back on bass but Bonnie Misses the music and preforming. So what's the perfect compromise? Bonnie now plays drums. Afterall he IS a rabbit and rabbit's are known for stamping their big bunny feet. They could rig him up with an upgrade that helps him hit the bass pedal on a drum set and it'd work out thematically. Bonnie gets to jam with the band and preform, monty keeps playing bass and the WHOLE band is all together again
This has been rotting my brain since the dlc came out so I just HAD to throw it out there
