Adjust cam timing without vanos removal?

FWIW Einlass = Intake, Auslass = Exhaust.
Anyhoo

According to INPA, my exhaust adaptation is 14° out, and in the red.
I don't think the mechanic that replaced my vanos bolts got it right.
Car runs OK, and no SES, it just bugs the heck out of me.

I've done much Z4 and M3 forum searching, and I haven't found anything on cam timing that didn't involve vanos repair.

Does anyone know if it's possible to set the camshaft 180° from TDC, loosen the 3 accessible hub bolts, turn it to TDC, lock the crank, and loosen the other 3?
Then use the cam timing tool to get the camshaft correct and retighten?

Two places where I think this could go wrong:
1) Being able to set the splines with the right amount sticking out. Possibly could rotate the camshaft before loosening the bolts to set the spline position, then loosen the bolts and set with the cam alignment tool.
2) Retightening the bolts in sequence, and to the correct torque.
