The compound radius will make it feel a little different than an Ibanez, but as noted above that'll only be the case on the lower frets and it actually feels pretty nice. So the Q is whether you want something more authentically like an Ibanez or you want something that's a little cheaper and that you might feel as or more comfortable with, depending on your playing style?
Also, if you're having this neck built and you're handy with some minor woodworking skills you might consider getting a paddle headstock and shaping it like an Ibanez. I got pretty close starting with a mooncaster neck, which had nearly enough wood to reproduce the Ibanez shape. I was replacing the neck from an Ibanez JS2000--which is very stratty in profile, radius, frets, etc.--with a Warmoth mooncaster with the Wizard profile, compound radious, and SS6100s. Here's the before-after on the headstock reshaping part of that project:

I did a lot of add'l work to that neck, including scalloping the fingerboard, fret end dressing, rolling the fretboard edges, and a level/crown/polish of the frets; I also had someone paint the headstock to match the body. This is now on an Ibanez JS1200 body and the guitar feels a lot more Ibanez-y than it dd with an actual JS neck on there! All that's left is to eventually replace the Fender style nut with a Floyd locking nut, but it works well enough even without that so it's not urgent.
