Hey man, I wrote the book on lazy, so no worries there. Definitely post an update if you do it.
I was thinking about it for a long time, which is why I looked up the relevant threads, but in the end my situation worked out that I just picked up an Essence (I mean, if it's 300 or whatever for the upgrade, well you're already a little bit down the road to another bass). A lot of people here love their filters and Qs for sure, and I really dig the filter on the Essence (am considering getting a Q for it), but I'm glad I didn't just get upgrade on the Epic. The Epic was my only bass for ten years and I was very used to the sound and controls. I dig the Essence, and I honestly haven't picked up the Epic since I got the Essence (only a month ago) but I'm still not sure which I'll take to my next gig... in other words, there's something to be said for familiarity, and bass/treble cut/boost is very simple to use on stage. To each his own though, I think most on here will tell you to go for it, and I can't really argue.
