I got this idea from the remakequake project, basically, The remakequake mod can read Quoth and nehahra maps, and replace their weapons/monsters with its own, thus creating a new playing experience.

Something like this could potentials work for Blood/Duke. The Blood port can read duke maps and replace the enemies. Of course the items and monsters won't match up exactly, but with a little bit of tweaking I think it could work. Some of the medieval/horror duke maps would work really well with Blood enemies and weapons
