So, sure. If you reduce sail by about 50% or more and otherwise ruin the boat or turn it into a displacement trawler.
Keel depth also affects pointing ability into the wind.

Naval architects crunch a LOT of numbers to get the keel right. Noodling with a pencil on napkin is not how to do it.
The right answer is going to be "sell the boat and buy the one you need."

Chuckles last sentense is dead on; you will change the lateral plane, CG, pitching moment, righting moment... everything. If it can be done right, it will cost what the boat is worth. Better to exchange.
