It's for this reason that people typically use VPW2 for the base for "No Mercy edits". Like the Freem edition of VPW2 adds more or less all the big WWF/WCW names from those games respectively, and even the ones which only use WWF/WCW guys exclusively still typically use VPW2 as the core to mod from because it's just the most finalized version of an AKI game.
TL;DR if you've ever played a No Mercy mod you've already played VPW2
