Minnesota seems like the kind of state where Democrats might go for a light-to-medium gerrymander, like Indiana or Wisconsin last time. In practice that probably means the 7th gets cut up between the 6th and 8th and everybody else gets shored up.
That probably means a great northern district--if Peterson holds on he'd have better odds with Duluth and the Iron Range. It'd probably still be likely R but probably more favorable than either district is currently.
Of course, this is all assuming that Minnesota loses a seat...
realistically, they'll draw something like this. It's not the best dems could do, but without cracking the twin cities or drawing weird districts, this is a pretty solid 4-3 map.

Yeah, a map like that would make a lot of sense. You could probably help democrats by dropping Carver and Scott counties and picking up Rochester instead if Democrats are willing to concede the 1st.
Playing around with a version of your map on 2016 population; not done yet but so far some of these districts look like they have some population imbalances which will need correcting--which makes sense since Minneapolis is growing even as the state is losing a district.
