Hi Villicus!
May I ask why it has to be a European shop? There are some guys here on the forum who have specialized in "copying" Ibanez and especially JEM guitars. A starting point I could suggest is to contact Eddie from EKG Guitars. AFAIK he makes bodies, but I am quite sure he can give you the right names for such a job! I can also give you some German luthiers. But none of them has specialized in Ibanez guitars. They are quite expensive too and are not really capable IMO...
Btw, I did a trip to Milano last summer. The traffic was HORROR!!!
Hope I could help you a little bit...
