The notion that Romney would have won under a different electoral college system is dubious.

6. The result of such a system is not "team Obama" in the suburbs

It's "team Obama" not in Ohio. At all.

Rural districts aren't suburbs. They're low-density rural districts with strong right-leaning tendencies. Your rally has 2 dozen people, and maybe you can convince 6 to change their mind. All for one electoral vote.

Not worth the effort.

As a result, the presidential election will look even more like the house election, because national-level resources simply won't be deployed to the states that do this.

And the election results might even end up surprising Repugs, in a bad way

Again, we just ran the two systems side-by-side, and Romney won in the system the Republicans are pushing. Estimates are the Democrats need to win by 7% to win the House. Campaigning "in the suburbs" for single electoral votes will not result in a 7% margin of victory.
