Looking for these locomotives in HO scale

[MLW]

Hello. I am looking for the following locomotives (Electric) in HO scale.

I have no idea where to start. It can be safely assume that these loco, as they were, do not exist in HO scale.
However, I am willing to do some "tweaking" such has: installing pantograph, new paint and some minor mods.

That way I can have a final product that would look fairly close to these two very different type (pictures below).

Sooooooo if you could point me in the right direction that would be great. I think that Bachmann may have something like the first one and maybe some European manufacturer for the second one.

I am just at lost where to look.

(1) Class Z-5-a, was built by General Electric in July 1950 :






(2) Class Z-1-a, was built by General Electric in 1914






I do realised there are two different type (above). It doesn't matter which one, as long as
I have something that is "close enough" that would work.

Thanks for your help
