Personally I like the 27+ platform, especially now that you can get 27 fat tires. So even if you are running a 1 X 11 set up you could run a 27.5″x3″ on the rear and 3.8″ up front, which is a rad setup. I built one up like that and it was sweeeeeet!
If you have the M30 Cranks stick with them for sure. I would see no benefit in switching.
For What you have described the Dreamer would be the ideal candidate, however if you think you are going to want some wider rubber one day then the Evasion would also work great and has been used in the D2R2.
