I like Donn Inversion. The ACBL approved defense to 2♥ = majors has a 2N bid as 15-18 with normal systems on, so I assume there is at least some merit to this treatment, though it is intuitively unappealing to me. It is so hard to judge whether 3N or 4M is a better contract with known bad breaks that I would rather just lump all of these hands into "bid 3N and pray" while having good ways to bid my strong minor hands. Also I think the people who would like to play systems on will agree that this treatment has no merit at favorable vulnerability, since your LHO is probably 5-5 or 5-4 with strong suits. As an aside, a 2♥ opening as weak in the majors is very effective when it comes up. I'm not sure it is the best meaning for this bid in the context of playing multi 2♦, but I bet it's up there.
