I think they have a lower temp threshold, so you would have to run very rich to keep the EGTs down. However, yes you can run a supercharger on hyperteuric pistons.
They are generally stronger and lighter than other types.
They are dimensionally stable, more so than other types.
They tend to resist hot-spots better than other types.
They tend to resist carbon build-up better than other types.
The drawback - while they are stronger, they are also more brittle. Think about an ordinary concrete block - you can stand on it, build with it, and it's very, very strong. But give it a shock load (hammer!) and it falls to pieces.
In the above analogy...
Concrete block = Hyperteuric pistons
Hammer = DETONATION
I've run hyperteuric's in boosted engines before without any issues, but I paid serious attention to knock, timing, exhaust temps while tuning to try and avoid reaching the point of detonation.
