Nobody has ever bought a ticket thinking "men in dresses are funny, let's see that."
The premise in SLIH is the same as SISTER ACT - "escape danger via an outlandish disguise" - and the show flies or fails on what the writers build on top of that well-understood premise.
Cross-dressing is inherently interesting because it implicitly critiques social conventions of various kinds. At the moment it's under intermittent attack (from all directions) by those who confuse how we enact gender with how we inhabit it. It's stupid, but it will pass.
