Nope, won't happen.
The multi piece wheels are multi piece for a reason, it's necessary to install the tire.
Newer one piece tubeless wheels have a dropped center that the bead nestles in while it's stretched/slipped over the rim. You can not put a tire over the rim on a wheel without a dropped center.

If your wheels are good use them as they were made to be used.
