Hey man!
EMG is selling the 808 pickups, that's an 8 string version of the 707 (or 85 in six strings). You can get them fro 101 dollars

You can also use the EMG 40 or EMGHZ 40, they work also. You have Lundgren, that are hand made, but they cost like 200 dollars each. You can get them thru conklin.
I used that tuning on a 6 string, considering that it was 25,5" scale, a 0.75 string worked like F#. But it was a bit floppy for my taste.
You can use a 0.10 pack of strings, and use a 0.75 for the low F# and maybe if you like tighter tension you can use a 0.11 a 0.65 for the B and a 0.80 for the F#.
The new Ibanez can handle the F# on a 27" scale, so i think that it will work.
