Any Issues Running Doom64 TC on Doomsday?

I asked this in Tech Support and someone directed me here. Since the existing sticky thread really doesn't answer my questions, I'll repost here:

I just downloaded Doom64 TC and it didn't take long to see it was built on the Doomsday engine. I copied the D64 wad to Doomsday and it runs fine. But it also inserts the 3-D models, skypacks, and music from Doomsday.

So is the reason for keeping D64 a separate program just to preserve it's original sprites and music? Or are there other reasons why it's not a good idea to run D64 TC on Doomsday? OK... there's a few new monsters and weapons for which there's no 3-d models. D64 TC reportedly removed multiplayer support because there were problems. Will there be also problems on Doomsday? Or is a wad a wad? I don't have anyone to play on-line D64 so I don't know.

Instead of having another version of Doom around... can't D64 TC just be officially added to the KickStart list where it could run in its original form AND have as an option the use of the 3-D models, yet keep the original D64 skyboxes etc?

EDIT NOTE: Doom64 TC doesn't seem to be as stable as Doomsday 1.8. It can not remember the screen resolution and keeps going back to 640x400 and after I installed the music pack, when shutting down the game the music just kept playing, and stuttering and playing. D64 was not running in the task manager but IE soon stopped responding and crashed.

Even if D64 TC can't remember my screen resolution it does run the intro screen and credits at a higher resolution than Doomsday.
