Lower Unit swap question.

I have posted a few items here regarding my 1978 Johson 75 Stinger.
With help from several good folks here I managed to get my engine running quite well. Near total rebuild.
Recently I acquired a 1971 or 72 Evinrude 115 on a Bayliner.
The motor itself was moderately burned in a fuel leak fire.
Don't have time now to look for replacement parts needed.
However, my Johnson 75 Stinger lower unit was badly beaten before I bought it. I did put in New water pump and replaced all seal in the lower unit
Including new prop.
My Idea is to swap the 115 Evinrude with the 75 Johnson lower units. They appear to be exactly the same except logo and colors.
Both long shaft...identical bolt pattern and identical prop shaft.
The 115 has a heavy steel prop...same pitch but smaller diameter
Blade swing.
I have a new aluminum prop I plan on putting on it.
Here's the question:

Is this swap compatible and feasable?
Already have both lower units removed for comparison.
