Reverse 5♥ and 4NT followed by 5♥ Marlowe. That way you can correct 5♦ to 5♥ with the rounded suits without partner getting excited. This is the inversion I was referring to earlier.

We play direct raises as competitive.

We play reverse good-bad 2NT, i.e. the good hands go through 2NT, the weak hands raise direct, and we just
do the same when 4NT is good-bad. We follow Marshall Miles, who is not known, to always recommend the standard
practice, but it works (... at least reverse good-bad 2NT / I dont have lots of experience with good-bad 4NT,
very rare).

I'm surprised that there seems to be some uncertainty about the meaning of 4NT. I'd assume that it's two places to play even without any discussion. I probably won't live long enough to ever need it as Keycard.

I think 4NT is the standard inversion - 2 places or competitive in hearts - and a direct 5♥ a slam try. Seems an easy decision from there.

In this auction I think it unwise to invert 5♥ and 4NT..5♥. If you bid 4NT and the next hand bids 5♠, partner won't know whether he's facing primary support or not, so he'll have no idea what to do. The inversion should only apply in situations where the oppnents are unlikely to bid again.
