'Curb' Star -- I'm HOPING For a Spin-Off!

Joanie and Chachi did it ... so did "The Jeffersons" ... so ya think there's a chance Leon from "Curb Your Enthusiasm" can lock down his own spin-off too???


We spoke to JB Smoove in NY yesterday -- who told us he's already come up with a couple of titles ... just in case if the powers that be at HBO ever give his character "Leon" his own show.

Keep your fingers crossed.
