If you bottomless pit is some sort of print, perhaps on high quality vinyl, you might get away with a sheet of acrylic and have the acrylic just sitting on top of the image.
However, I don't have much confidence that this will give you the effect you really want. I would suspect that you would really wan to have some actual drop (say 3 ft just to guess) and then use a print to give the bottomless pit impression.
IN that case, you need really thick acrylic to take the weight. You might get away with only kinda-thick acrylic if you build it into some sort of grid where each block is only 6"x6" and supported by a metal frame.
All in all, sounds like an expensive prop that might be hard to pull off.
Just my 2c either way.
