If you are happy with what you have, keep playing it. If you have access to other high end basses, try some out.
If you decide you want to go that route, DO NOT sell or trade you P. You will not be happy you did. And, if you decide you liked playing your P more, you'll have no regrets.
I have always owned mostly American made Fenders and G&Ls. I have some Squiers, an Ibby, and some acoustics. My favorite was my G&L SB2-T. Recently, I went the same route you are contemplating. I saw a bass that looked exactly like I think the perfect bass should look. well, like this:

I am happy I made the decision. There is definitely a difference in how it plays and sounds. The first thing I notice is how comfortable it is to wear. Although it is about 2.5 lbs. heavier, it doesn't bother me at all. It is so well balanced it hangs perfectly. I can take both hands off and walk around and it is as level as can be. There is nothing left out on tone control. I know, because I'm primarily a P guy, that may not mean much to you, but it gives you a lot of options. The tone is also very articulate. Each note is well defined.
It has become my #1. I'm even wondering if I really need 15 basses any more. I'm thinking of cutting back to my Fodera, my P Select, my SB2-T, and my Breedlove Jumbo.
The bottom line is few will know or care what instrument you play. So, focus on what make you happy.
That was not the bottom line. This line is.
