Neesey, If you don't feel right about it, don't do it. I have found for myself, the sooner the better. If you can visit an animal shelter, and a certain kitten touches your heart, you'll know for sure. There are many homeless babies waiting to be loved. If you can't bring yourself to go, by all means wait. Of course, no other cat can replace Lucy, so please don't expect that. You would resent the kitten for not being Lucy. Your next kitty will be its own sweet, mischievous self. Check out the "purr factor"-- that is, how relaxed the kitten feels in your arms, whether she wants to come to you, whether or not she is lively or quiet, (not how loudly she can purr, but if she likes you) and what your feelings are towards her or him. If you have always wanted a purebred cat, you might want to consider a breeder also. Do it in your own time.
