completely agree - i think he might get away with cunningham (i think josh gad was early-30s when he originated it) but that’s literally the last one i could think of! the pool for that type of role is small and he’s done most of them already
i would pay to see him with oliver too but completely agree that they’ll travel instead. they both know their limitations (though i admittedly did really enjoy carrie’s eponine) and this is all about creating their brand away from musical theatre.
edit: actually i’ll add the duke (or even zidler) from moulin rouge to my list for joel. he can do creepy, heck he’d be playing himself.
