That's the real way forward. "crossdressing" has a stigma because the very meaning of that word comes from gendering clothing. So you need to stop using that term.
But that was at SCA events, not a work environment. I don't think you'll find glass staircases at SCA events.
TBH, I'm not a fan of glass treads on staircases, I'm not a fan of glass rails on staircases, in fact I'm not really a fan of anything glass in any part of a stairway or staircase construction. Windows next to a stairway are okay, but I think that's about as far as I'd go.
OTOH, glass does wear better than marble, and marble is frequently pretty slippery.
So, maybe no marble treads, either. Some other types of stone would be okay (e.g., granite), but only if they were properly prepared so that they wouldn't be slippery, and would have rounded edges in case you fall.
Though not explicitly mentioned, this sort of thing is "gendered" in the sense that crossdressing still carries social and professional consequences (even for women, to some extent). Which is a shame, because crossdressing is awesome.
