Another thought: if you don't actually have a spare wizard neck lying around to slap on your strat, buy a Wizard profile neck from Warmoth. That will definitely fit your strat and you'll be able to get 22 frets and keep your fender shaped headstock. You could even get it with a purpleheart fretboard if that's what floats your boat
Also, Ibanez wizard necks have 24 frets, and fender necks have 21 or 22, so even with the same scale length the Ibanez neck would come in closer to the bridge on the strat, requiring you to route the body to fit it; essentially destroying your strat.
Warmoth
should be able to get you a replacement strat neck in a wizard profile for about 150, which is about what an old non AANJ RG neck would run you on eBay. Give it a thought. A Warmoth will also likely be a much nicer neck than the stock one, they make very nice replacement necks.
