Since you ask....
First, let me say that this is a very subjective area -
That said - here's my "Subjective" take: I hate the sound of a EB-9. HATE IT. All of those old Gibbys sound like a mud-fart to me (and yes, I've had an old gibby - my first bass was a mid-'70s EB-1). And I quite like the sound of a rick with a set of zingy steel rounds on it... It's iconic, and, for what it's trying to do, virtually perfect. Why muck with that?
I get the wanting the "best of both worlds" thing, but I suspect that by replacing the front p'up of your rick, you're just... well... "De-Rickifying" it. If you're cool with that, okay... Good luck reselling it - but me, were I in your shoes, I'd leave the Rick alone and get a EB-0 or EB-3. They're out there to be bought.
Like I said - this is a pretty subjective thing.
