Post a link to it? And it doesn't really matter if you have 2 or 3 pickups exept for that you can be more versatile with 3... what matters is how good they are.

I would say no for 2 reasons, Epi pickups suck and in this case you have to replace 3 not 2 if you want them to sound good and although I've not played one I have read in reviews about complaints to do with the middle pup getting in the way when strumming, this may not be a problem for everyone though I don't know.
