Stress is like water it is dynamic and it changes in conditions a structure is placed in. I know we all only want to fix stuff once but if you have the skills to make this modifications. You have the skills to fix anything that brake or fails afterward. I think any reasonable repair or accommodation is better than nothing. I say use the materials you can acquire locally and since we can’t test it live and learn.
To your point, if I have the skill to take it out, surly I can put it back. Think I will be doing this mod. I think down the road I will be much happier this way especially since it’s a real option. Have both tranny parked on the shelf in the shop......
