At this point I'd use the IP timer or heavily padded grips on the IP drive shaft (timer removed) to center the tang in the RIV port and confirm by fitting the locking tool. But first, I'd loosen the IP and set it so the bolts are in the middle of the adjustment slots.
I've never done this but I read about slipping a stiff sheet between the chain and timer - giving up positive indexing which could lead to problems later on - all the way around timer where it's in contact with the chain. I also read about heavily greasing the chain and pushing it away from the timer with the grease holding it away from the timer.

You have pretty much made my point that it cannot be done. Thank you.
The cams can only be locked at TDC.
You can get slack beyond the cam gear by removing it from the cam after the cam is locked, which you cannot do at 15 degrees after TDC.
I noted the impossible procedure to make my point that it is easier to R&R the IP than to try to R&R the timing gear, that cannot be done anyways.
