Not advisable in my opinion. Even while Magnepans present a rather consistent 4 Ohm load, it would be pretty hard on bridged XPA-2s. Can't move to XPA-1s?

Hello the Magnepans outside of the audible range the impedance will very low. Potentially down to 1.6 ohms. It is not recommended to bridge the XPA-2 with a speaker that is lower than 8 ohms nominally.

I'd be willing to bet a single XPA-2 will drive a pair of Magnepans to extreme SPL with little or no clipping. With 500wpc on tap into 4ohms there is plenty of power. If you simply *must* have more power then the XPA-1s should be the next consideration.
