Westwood, Oosthuizen, Watson, Mickelson, and Poulter are now in LIV. I'm not necessarily saying any of them would be on the list, but it's worth pointing out the 1/3 of the 2012 list is no longer part of the PGA.
I definitely believe none of those guys would be in the top 10 even if LIV didn't pull them away. That 2022 list is all very young and Rory is the elder statesman.
