Someone who is actually done it may have a definitive answer but with shims, anything can be changed.

 

im sure people have used little strips of emery cloth as it grips and doesnt slip out! dont know how it affects your intonation tho!

 

You can buy specific shims that would fit an OFR or Edge, for a rounder radius you woiuld add some height to the D,G. A, and B strings depending how much adjustment is needed, you can also use pieces of foil or another material that will give height to the saddles...

It's not too difficult really and can easily be changed or added to if you need more height!

There may be some usefull info on rich's Ibanez rules site but im not 100% on that you could also cut shims yourself I believe many manufacturers just use some copper placed under the saddles that need raising...

I've have taken plenty of ofrs and alo pro apart so it's not difficult to reassemble, just be carefull with the metal washer on the saddle bolt screws as they can fall down,,,,

 

Hey thanks guys!
I have decided to sell the guitar (JS 100) and simply get a JS 1200.
This is good info to have though, for sure!
