First I have some unfinished facility and complex maps that I created for solitude, I might feel compelled to finish them. And would glady donate them.
As far as the suggestion, I would say to cancel on modding quake yourself. Wait or work with Solitudes devs to build off their engine. It seems most if not all features a Goldeneye remake are built in. Just have model replacements and unique muzzleflashes and animations, etc.. It should work out great.
