I mean...I suppose it might be possible...but, since HA DIO would have known what both Johnny and Giorno's Stands could do (through Funny Valentine and Giorno's revived and enslaved allies, if not through direct observation via an ability to see into other dimensions), he'd probably already granted himself and his Stand immunity to their abilities, using TWOH's reality rewriting ability. Or at least knew them well enough to predict their use.

It's also entirely possible that The World Over Heaven has the same sorts of immunities that GER has, or possibly even more immunities, just by default.
