Mississippian #76/77 Gettysburg, etc.

I am making a kitbash of Missisippian #76 and #77 using Ben Neal and trainboi1 stuff. One will be lettered for Gettysburg circa 1980's and the other for Alberta Prairie. #76 is actually stuffed and mounted in western Maryland now as a B&O 2-8-0 with a tender from Arcade and Attica #18, and #18 now has #76's tender, and is undergoing teardown and rebuilding. Would I be able to get permission to upload these? Ben is pretty ok with reskins, what about Trainboi1? The locomotive model is the Washoe #72 from Trainz Forge, and the tender is the one from Ben's NYC 0-8-0. I am replacing the drive wheels on the locomotive to make it a 2-8-0. Probably with wheels from one of Ben's or Trainboi1's locomotives. You just replace the kuid in the config.
