Man you might be able to create a whole prop pack with those! I'm worrying it a bit about the map performance though since it has so much poly.
EDIT: Wait, are you making the prop set for distribution? or for your map?
polys are usually not the issue, eeerm....meaning that good ol source usually plays pretty good on decent mid-range computers now days, but overall less fancy stuff where combat happens and more fancy stuff where combat does not happen, ..., those beams are 500 polys per piece, currently the spawn has less than 10k polys...which is close to nothing, as long you are only seeing a few rooms I'd say 30-40k static polys are within range, but you always have to leave some room for hats etc, especially if you are doing it with 12ppl on each side - all with fancy hats, thats 15-25k polys right duuure...meaning you have 10-20k polys to play with, (take these numbers with a grain of salt,)
wasn't going to release it, but if the stuff turns out decent I see no reason not too - only issue is if you are releasing stuff for others to use you need to have a decent - or at minimum, a understandable naming conventions, lods etc...the props are very situational and other users might expect more things to fulfill their vision, its also a theme you cant mix with any of the other stuff you find in tf2 so you would be very limited with the ~80 or so props provided here, which might not be enough to cover your needs

will make a decent tutorial after the Holiday madness! promis!!!!
