I know this won't fit your list because it uses "original assets", but a long time ago I uploaded a fan-made remake of DOOM 64 to a freeware game site. The trick was that I used FREEDOOM.WAD to power the game instead of DOOM2.WAD, and it still works!

P.S. There's a better fan-made remake out there now called DOOM 64 EX, which is more faithful to the original game and also has multiplayer support. I can't provide a precompiled package for this one though, as it requires the original N64 ROM to be converted into a DOOM WAD.
