I worked on M1A1 Special Edition and M2 Special Edition with Raul Bonilla and others back in the day. I recently switched up some of the music for the M2 Special Edition (but had to rename the new music to the old music file names as I no longer have access to my old Mac emulator for editing with the original tools).

They come with 1024x1024 JPG textures from Tim Vogel's Total Texture Enhancement Pack 6 pre-loaded, and custom MML and Music files, plus modified Shapes, Sounds, and Map files, but otherwise other files are copied from your Classic folders (so I can start your Classic games and have the Special Edition version play within Steam on my computer, so the modifications are already done, they just need their own page).

Maybe the M1A1 and M2 Special Edition scenarios could be listed too (for which I can provide the files and $100 upload fees if you wish to list them on Steam separately)?

You can use your existing Achievements, plus a couple new ones for each (i.e. Fists of Fury: Take down a Drinniol with brass knuckles).

Tim Vogels TTEP 6 Pack (with 1024x1024 textures) can simply be made available as DLCs in Classic versions of the original Trilogy you have already released.

Any chance you guys will upload some of the popular Scenarios as standalone Steam games, like Evil, Tempus Irae, Trojan, Rubicon, and Eternal? I know these will take time as you may need permission of the original authors and will have to determine the game Achievements.
