Heck, John might even be able to make his Armorlock shields stretch out to protect multiple people now.:p
As for radioactive stuff, John has a Fusion-Plasma Hybrid Reactor powering his suit.
Dr.Wily could remove the fusion material from John's suit (I think it uses Deuterium) and put Bassnium in its place.
The fusion would then be powered by Bassnium.
