Hope you get around to the Nod EVA list.
Also you could include the NODEVA.mix with dummy files with the proper names and then,
then I could replace the dummy files with .AUDs and the conquer.ini, there should be a line which says something like:
CustomNodEVA=0, changing it to 1 would make TD read both speech.mix and NODEVA.mix
Oh, you fixed the TD prerequisite bug? I remember back in the day, only certain structures could be used a prerequisite for units/buildings.
I take it you've made a custom editor to mod this TD?
I conclude the viceroid in TD and the visceroid in TS are two different species.

They look different and attack differently and viceroids don't need to fuse together to mature.
