I won't be able to answer your question, but to save us all some time and space, it might help if you explain what you mean by love it.
Are your J and Elan also fretless, or is that a factor? Do you like the feel of the P? The sound? Probably both, but let's assume that it must at least sound good to you or you wouldn't be so enthusiastic. (If it's mostly the feel, then you could closely approximate at least the neck shape and string spacing on any custom.)
What is it about the sound that interests you, and how would you compare it to the sound of your J and Elan?
Also, tell us a bit more about the construction of your J and Elan, in particular the woods (i guess i didn't know you could get Fenders with a neck made of something other than maple, but your Elan could be almost anything).
I've never played any of these outside of a guitar shop, but there are plenty of others here who will be able to make useful comparisons - as long as they understand what you're looking for, and why.
