Doomsday Engine

Using Doom 64 EX as a basis/guide, create a new (or heavily revised version of the) Doom 64 plugin that is more accurate in terms of gameplay and uses the original Doom 64 ROM for data assets.

The old Doom 64: Absolution TC should be kept as a separate plugin (in maintenance mode), because it is substantially different (based on jDoom) and uses a custom-made IWAD file rather than the original ROM.
