I don't think you guys understand just how much would be need to be raised to make this work.
Last year I asked HiTech how much it would cost to add a Bf 110F. It would require only taking elements from the existing 110C and 110G 3D models and altering the files to factor in the new weights, and engine power figures. I even offered to make the default skin.
He gave me a rough dollar estimate for this fairly simple task and it was shockingly high.
Put it this way, if every player that participated in the last frame of FSO donated $100 each, (just to illustrate a small, yet definable subset of the player base) it would not cover half of the estimated cost for one modification of an existing plane.
