yes, with only minor changes, although it depends if you want to do the early one or the late one. if you are going to do one do it with the flaired radiators instead of the flat side ones like on the mac, due to the fact that the SD70M with the flat side radiators is already being made by a member here, almost done too so if you guys did that it would kinda be like a shot in the foot for him.
some info on this version of the loco:
Starting in mid-2000, the SD70M was produced with SD45-style flared radiators allowing for the larger radiator cores needed for split-cooling (split-cooling is a feature that separates the coolant circuit for the prime mover and the circuit for the air pumps and turbocharger). There are two versions of this radiator, the older version with two (2) large radiator panels per side, and the newer style with four (4) square panels per side. This was due to the enactment of the EPA's Tier I environmental regulations. so basicaly this is the one we need.

(not too much work for doing this, just a few minor adjustments in the rear and on the front windows.)
