Could someone make these or point out where to get them?

[Whatzizname]

I was wondering if some of these items have been made, or could be made for railworks

Sorry about the low quality of the images, as they are from old youtube videos
They are all in this Link

I just have a couple requests
That the Orange face SD60 be put on a SD40-2 and
That C&O (Chessie system) 8245 be a dash 7 instead of a U-Boat

Thanks in advance
