Great comparison mpe!
Regarding the pipeline issue on the POD - I can't imagine that both pipelines can work on a 4 byte bus, and if they do they would "interleave"(aka no idea how it would work).
Maybe it's possible to find out via the instruction complete signals of the cpu - each pipeline delivers one maybe this could solve the mystery(V-Pipe completion signal on pin B01 according to text).
Yes, Doom is not really "scaling up" nicely on newer processor but the demo of E4M2 in the Ultimate Doom is a VERY strong indicator of firepower for lower clocked Ps or high clocked 486s.
Do you know any method of improving the timings on these old Mercury boards maybe via a "hacked" BIOS?
