I see most crosscut sleds use 3/4" plywood for the base, but why
couldn't I use 1/4" Lexan instead? It's a stable material, isn't it?

Lexans attribute is that it does not scratch as easily as other plastics.
I use 3/8 all the time for jigs. It is used as trays and stuff for
wheelchairs.
1/4 is a little thin for a sled but I think it will work if you are
careful. Chamfer edges, holes and slots; cracks will propagate.
