If the story was worked on enough that it flowed together, SFTBH on stage could work. Without doing any work to the story, it would not be a good show.
I could see Rivers creating a musical in collaboration with a range of creative people. It wouldn't necessarily have to be a Weezer project as such, perhaps something independant of the band?
Even though I'm not a huge fan of musical theatre, I think that there's potential in the idea. So that would be a 'yes' vote from me.
So are these yes's to the vote? or no's...cuz ithink itd be cool
