Probably just need a longer chain. 36T cog is 4 teeth bigger than stock big cog, so you'll need a chain with 2 full links longer (4 half links).
Slight possibility the RD can't handle things but it probably can.

Constant tinkerer
The more I think about it, the more I am leaning this way. I considered the 1x sprocket on the front (suggested by Frank Cannon) but there is a decent amount of road riding with this bike and I don't think 1x would provide big enough gears.
So I saw the link from ColonelSanders (thanks!) which brings up another question on crank / BB compatibility:
Was looking at BB's and saw this: Shimano XT-SLX BB70 Hollowtech II Bottom Bracket
I *think* this will fit in my bike - PLEASE confirm someone..
but it doesn't look like those SRAM crank arms will fit - correct?
Just trying to look up info and it llooks like SRAM cranks / BB's are incompatible with Shimano? I'm not necessarily trying to solve this Rockhopper issue at the moment just trying to learn and figure out what my options are - I have a couple other bikes that may need fixing up
