I'd kill, and I mean KILL to see an advanced DOOM port make it's way to the Amiga.
I see that Amiga OS 4 has PrBOOM, which btw should be on EVERY Amiga port as it is very compatible with classic DOOM, but also removes some bugs and limitations whilst adding in a few subtle features that really go a long way, I.E. Translucent Windows, Ice, Mud, and Wind Effects, Multiple Skies, Rotating Skies, Man's Best Friend (a protective drone), etc. etc. etc.
Now what would be awesome would be to have a port of GzDOOM, but as fate would have it, our Graphics Card Drivers are lacking, thus we would be un-able to pull of this port's more advanced effects:
I.E.:

While it may be lacking of few of the more advanced features that GzDOOM's hardware acceleration support brings to the table, it's still capable of doing quite a bit. One such thing is 3D Floors, Free Look, Sky Boxes, Advanced Scripting, Endless Weapons behavior, endless enemies, you name it, it probably does it, plus it supports all the DOOM WAD files as well as Hexen, Heretic, Chex Quest, and Strife!

My guess is if there is a DOOM Rally, then it was probably written for ZDOOM.
