Careful, you've included a really big assumption that hasn't been written into the rules. Consider a being with Magic Might inside the Aegis of the Hearth. It tries to use a R: Personal power with 0 penetration on itself. The effect is resisted, yes. However, that means the penetration is reduced. This means... it still works because there is no resistance. (Negative penetration is OK if it doesn't need to beat Magic Resistance.)
The issue is that it doesn't say how items are resisted, just that they're resisted. Meanwhile there are different ways of dealing with resistance (spells vs. powers). See here for more information: A Guide to Aegis of the Hearth
This is why I only warned caution. Aegis of the Hearth is not necessarily an issue alongside ReVi suppression. It depends on how you play the Aegis.
