No worries. I have done this to my 10x12 shed when I built my garage and re-roofed the house. That was in 2005. No issues at all. There was nothing wrong with the shed roof, but I wanted them all to look the same.
My original roof is 3 tab shingles and I covered it with dimensional shingles which are sorta twice as thick. Appearance wise it looks a little thick on the edges, but not that noticeable. I can snap some pics of you like.
Disclaimer: Im not a roofer.
This worked for me. Where you live in Idaho and probably get snow in the winter, you may want to consult a roofer or engineer in the area about the additional load on the trusses/walls/foundations etc.
