We haven't discussed this as much as you obviously have, but one difference we have which might interest you is that 3 of our major asks for help in that suit and 2NT is competitive. As you say, using 3♠ to compete makes little sense and 3♥ is impotent.
I think this is not an improvement. If you have a competitive hand you should shut the opponents out of the bidding by raising to the level you want to compete at and stay there. Using a conventional 2NT (presumably forcing to 3 of your suit) gives the opponents an entire round of bidding space. On other auctions I
do use 2NT as an artificial raise (typically invitational+ with at least a 9-card fit), but it is decidedly not 'competitive' (and it also sets up forcing passes depending on the vulnerability).
Depending on the auction there is more or less need for game tries, competitive bids and penalty doubles. In an ideal world the methods would reflect this need. As an example, on the auction I gave earlier (1
♥)-1
♠-(2
♥)-2
♠; (P)-? I think there is no good reason to play 3
♠ as competitive. The good guys have already won the auction, responder is unlikely to change their mind and come in with 3
♥, and even then you can just bid 3
♠ after (and if they come in with a lead-directing 3m, so be it). Conversely, on 1
♠-(2
♣)-2
♠-(3
♣); ? it is valuable to be able to compete as well as try for game. If you really want to use the bleeding edge of competitive bidding tools you would play different systems in these two situations - for example, different shades of game tries for 2NT through 3
♠ in the former situation, but competitive 3
♠ in the latter. I'm personally not good enough to stay on top of all of this (and I had one funny misunderstanding where the bidding went (P)-P-(P)-1
♠; (P)-2
♠-(P)-3
♠ which was intended as competitive, but partner assumed a game try because there was no real need to take out protection just yet. It turned out our opponents simply did not have a pulse), so I just stick with a similar scheme in most situations.
I think Kit Woolsey's suggestion of using 4M as the game try is very sensible.
