Although the durability of the N* and it'* head gasket issues leave quite a bit to be desired. I doubt a N* would hold up to the added stress over any amount of time. Not to mention that the availability of used N*'* is quite limited. Many yards won't sell them because of the HG reputation and their experience with the N*.
As Venom mentioned in another thread, it'* best to either buy it new or skip it.
Supercharging one would be interesting. I suppose you would need to fabricate lower intake from metal to withstand the positive pressure..
