You can. the cassettes exist and you just need a goat link hanger, of which there are many. Your main concern will be the massive jumps between gears.
@TotalShanner Not disparaging the existence of 12 speed. I'm all for it, but 11-46 was already there, and 50t expander cogs have been about for a while for 11 speed, hence my comment about the 10t since you want the benefit of both on an MTB.
I tried the expander+extender and it never really worked properly. 11-46 doesn't work for weaklings like me. Every time I get to that disgusting climb up SDW at the end of london to Brighton off road ride I wish for an even lower gear.
