Is it possible to change the operating limitations of your homebuilt

Let me take the more extreme case...
I was wondering, if one owned (or bought) an RV3, is it possible to
change the operating limitiations to have a red line of 120 knots, and a
maximum continous RPM that arrives at a speed or 120 knots?

Yes, you can go through the process and change the operating
limitations of a home built.

This would potentially make it fit as a sport pilot airplane (when flown
within the operating limitations)

NO, Any airplane once outside the sport pilot limitations can *never*
be brought in, or back in if it had been there before.

Technically you could initially build the plane with an engine and
propeller combination that would put it in the sport pilot category,
but you can not modify the very same make and model to fit the sport
category if at any time it's operating limitations would have put it
beyond the sport plane limitations.

I don't know how many other ways to phrase it, but once outside the
category, it will remain so forever.
