Heck yeah Ken. They mixed everything.
CP 8594-RS10 8458-RS3 4016-FA1 at Agincourt Yard June 1970.jpg

and...
An Amtrak F40PH with an SP E9B.

Finally I have video of an Alco RS-3 doubleheading with a 4-6-2 Pacific
Hope that helps.

In reality, there are a couple reasons why some locos could NOT MU as you describe.
First is that early diesel MU capability was not universal. Some, (like Lima, early Baldwins, and early FMs), used compressed air systems to control added locos. Others like EMD and Alco standardized on an electrical design. Some roads replaced the air activated controls with electrical later. So there could be compatibility issues.
Second is differences in gear ratios. If the locos have different gear ratios, then they won't MU together well. One loco will go faster at a given throttle setting then the other loco. Your idea would possibly have such a problem. Most E-units were geared for high speed while frieght only F-units would have a much lower high speed gearing.
BUT ....... again railroads did alter things. When their passenger carrying days ended, some roads did try to regear the E-units to use them as frieght locos. Most 6 axle passenger locos ran "A-1-A" trucks though, which did not do as good in frieght service. I don't think these lasted long.

Ken;
I know CPR and CNR ran FP-9A's with F-7/9B's as there were no FP-9B's.

CNVItyco:
You;re punching above your weight class there, vocabulary wise, Kid.
From context, I can deduce you understand the word's (Ubiquitous) meaning, but thats more than a typo. Turn on the spell AND grammar check I adjure you!
I think my eyes are bleeding!
