What to do with old quarq zero 5x110 bcd power meter

Ive got an old 110 bcd 5x110 quarq zero pm sat around doing nothing. Its bb30. You cant really get big 12 speed chainrings for it. It’s the 8 bolt spider version.
Can you get 8 bolt gxp mtb crank arms? I could chuck it on my mtb then.
It was a really good pm and was the carbon red version so seems a shame.
