Many thanks for the suggestions and help.
Perhaps I will share my project with you.
I picked up the SP 4449 with the extra tender from MTH years ago after many rides and photo trips on this stunning engine just had to have it for my fleet.
I picked it up in 2 rail scale but it does not have much pulling power.
I pull a string of colorful scale billboard ice reefers with it and found a couple of SP cabooses to use, converted to 2 rail scale wheels.
Again the engine does not pull much weight, I normally just run it in a loop all the room I have at home in the basement or on a large loop on a floor layout at shows. I really need more pulling power so I was looking at ideas for a pusher to help.
I found at a show quite cheap a Weaver E8 SP shell, looks good similar paint scheme to the engine at the California Railway museum.
Thought perhaps I would power this and use it as a booster engine with 4449.
But recently I came across a MTH Southern SD45 High hood for $150 a steal; low miles and full DCS proto 3 nice engine pulls like a tank. I picked up some 3 to 2 scale wheels sets they just swap right in for scale wheels.
I thought perhaps this would work well with the MTH Proto 2 4449 Steam engine using it as a pretend SD7 or 9 like SP used to run.
Thus I used an old Williams frame and picked up some dummy 2 rail trucks for the SPE8
And am now trying to come up with a paint scheme for the SD45 that will be close enough to the other 2 engines for a nice looking train. Perhaps as a pusher further back in the train? Again it is just more for a fun train some color to run at shows or just to look at running a long string of colorful billboard ice reefers on a loop all the room I have on my home layout.
I think this photo is what I am hoping to paint it up to nice looking scheme, think it will work best with other engines for era etc.

I should be able to mask off for the silver paint but the orange perhaps with some orange pin striping or mask and paint if I can not find the decals.
This engine is a SD9 at the Niles Canyon Railway;

Will see how the decals look that I ordered if they work the White SP lettering is the most important part.
