i think the closest guitar in production now by ibanez is andy timmon's signature, but that's about usd 2.5k new.
the easiest and most practical way is to heed wck's advise. the rg470ahz looks good! that's what i personally do to my H-S-S pacifica last time with two push-pull mods on my tone and volume control. they coil split my humbuckers in the bridge and neck respectively. after a while though, i found out i never needed to use the single coil on my bridge and now i've just opted for a parallel mod on my neck hb. my middle pickup remained as a hum cancelling single coil voiced pup.
if i ever needed a strat sound, my mid pup would do quite a good job at that, and if i needed a rounded strat sound, my parallel wired neck hb would cover that. apart from that, my options are still open for a bridge hb and a neck hb!
maybe you would like to consider these mods to widen your tonal options? i have a total of 10 fairly different tones on my pacifica now with just two push pull mods! (my other pp pot now activates my bridge pup)
