Yep, that might work. My first machine, a Singer post-bed that I was given, came with a clutch motor and the first time I fired it up it scared the daylights out of me as I had absolutely no experience with such a thing! Yes, I learned to drive manuals but feathering this clutch was NOT working! So I went through the usual things, fitted a larger pulley in place of the handwheel, made a speed reducer and experimented with various pulley combinations but to no avail, I could not tame this beast. It wasn't 'til I fitted a servo that it became useable.
Mastering a clutch motor can be done (just not by me), I wish you luck in your endeavors.
