Is the issue that the mech can't come back far enough inboard?
With the size of the chainstays and the narrow Q of the cranks there isn't a huge amount of room to work with, but I found that 1-1.5mm was plenty of clearance on the NDS between crank and chainstay, allowing you to have a degree of flexibility with the DS.
On a friends SuperSix there is an indentation behind the mech in the seat tube to allow it to come back in further than on the SystemSix.
I got an old SRAM Force front mech shifting fine, so it can be done.
