I wouldn't like to say how much you could shave off there as that would go through to part containing pressurized brake fluid unlike normal car calipers which only have a single piston so you can shave the outsides relatively comfortably.
If you have access to a lathe I'd be machining up custom spacers if you need the absolute minimum of offset added.
That said if you are good with an arch roller you can get inches out the front arches, pretty sure that was nearly 2 inches on my BMW below.
