More quick shifter questions-

New (To me) 2003 R6 has Volter Moto rear sets and a brandy new cordona push style shifter, set up for GP shift.

I don't want GP and want to return to regular. This looks easy enough as indexing the shift link on the end of the shaft from 6 o'clock to 12. This would keep the shift rod outside the frame, but would keep me from buying new rear sets.

Can the Cordona be re-figured from push to pull?
Thoughts?
