I sent an e-mail to Aardappel, creator of DMSP2, the awesome mod that places monsters in DM maps for single and coop play and asked him if i could release a hugely modified version of his mod, which could only be titled: SuperDuper DMSP2!
Plans: more monsters, more guns, more gibs, more PACKET OVERFLOWs! Tougher monsters, MORE GUNS! More Explosions, MORE GUNS!
You're gonna start over and base on his? Why not integrate dmsp into your existing source?
Good luck :D
