If you really want a new CS2D, please, go make one, go start just like Starkkz (and _Yank if I'm not mistaken) did and ask for help when you need it. I am 100% confident that people will be willing to help, but so far this has been all words and no play. I'm not trying to be judgmental here, it's just annoying to see 10 threads and 200 posts every year with people saying that they are going to overhaul the game or build a new one yet in fact no one actually does (It even took smn at least a year for his overhaul which is currently in use and he still needs to finish the maps).
If someone believes they can and wants to build a new CS2D in full (not just a single aspect), tell everyone here and now. You will receive the help you want in the aspects you lack experience or want to do.
One last thing, until the lighting and crashing bugs are solved the game will not be on Steam, that would be suicide and ruin any chances. Know that DC does care and wants this as much as anyone else yet is either too busy or cannot solve bugs in a timely fashion (or not at all).
