Pam Bono has a pieced rabbit design, very cute. But the only place I know it exists is in her book Quick Rotaty cut quilts.
Debbie Mumm also has a pieced rabbit design in her book Quick Country quilts.
Just found a paper pieced bunny pattern on Etsy too.

Maybe you could make it more Easter by putting basket blocks all around it.
