Interesting. That sounds like a very possible reason for the knock but i have a hard time believing they couldn't just retool for a piston with a different pin location after spending years of development on this bike. Second,  the notion or issues with emissions complacency sound even more suspicious due to the following. In the second model year of the Tbird triumph removed the air injection from the model from that year on because they said the emissions were so low it was not needed and the bike easily met the regs w/o it. Now granted, the regs keep changing but when a bike is THAT good as emissions go i can't see them being too polluting after a 9 year run and still without air injection that if true they certainly would have put back in in the later years of the model. So if i had to wager i would be that was company BS to save face for the real reason(s) which are likely poor sales and.or the knocking issue, both of which knowing triumph they would never cop to.
