I have a SZ520 that I put SD PUs in. A jazz in the neck and a Custom5 in the bridge. Now I can get all the tones you seem to be looking for. I used to have an Epi LP with the jazz/jb combo and it was a good guitar...but the ibanez is far superior in my opinion. Still if you love the LP look/vibe go for it. I love my SZ but I have been thinking lately of adding an LP clone to my collection as I still love the look of them. (probibly a Tokai this time) Alot depends on the amps you are using too....probibly affects the tone more than your axe, I think you would notice quite a difference with an all tube amp.
