Instead of PAUSE, we wait on a lock word with WFE. WFE puts a core into a lightweight sleep state waiting on a particular address (the lock word) and a write to the lock word wakes it up. This is very useful and somewhat analogous to 86's MONITOR/MWAIT. I can't immediately see how to generalize your proposal to ARM, which is a shame. Andrew.
