beagles out of good lines should make at least decent hunters, most of the time better then decent. you can even get lucky and find a pet beagle that will fit the bill....get them out young and often, or throw them in with older dogs if you can. we run year round down here, keeping them in shape and rabbit minded.
p.s. if your ever make your way down sw i got a training pen you can throw a pup in.
Pic from sunday, dogs caught this little guy after a few hour race.(dog on the far left was someones house dog until last weekend, she is on her way to being a rabbit dog.)
