Perhaps not even that is required - maybe there's something hidden in the primaris work that causes them to fail or go rogue or something, or it turns out that Cawl's actually been corrupted by Vashtor and all the primaris are now loyal to them as their own faction, but the high lords suddenly remember that they've got the best part of 10,000 years worth of samples of tithed geneseed from most of the chapters just sat around doing nothing.
