Specialized Cirrus 4 groupset upgrade (lemm.ee)

So I have a lovely Cirrus 4 that I call my adventure bike. Currently I am running the stock groupset that I would like to upgrade. This bike currently has a hyperglide hub and threaded bottom bracket. What I want to do is get a nice 1-by front ring and have a bigger range in the back. I am totally happy sacrificing speed for hauling so I would like to get something like a 42 in the front, and a 11-42 in the back. I don't have much experience with these lower tier groupsets and where the mountain bike compatibility starts and ends.

Has anyone done any kind of rebuild like this?

Do you think I would have an issue with a crazy chainline with something like this or should it all work fine? The long cage derailleur is good for up to 46 and the 36t in the front will give me a least a LITTLE speed in the flats.
