I used to play exactly this style - that a 1D response could have a 4-card major if strong enough to invite opposite a 1NT rebid. I think it has quite a lot of merit. (I stopped when we changed to playing transfer-walsh.)
You have more sequences than you can possibly need after 1C- 1D - 1NT, just invent meanings for all of them... (We played 1C -1D-1NT -2C forced 2D (which could be passed) then 2M as invitational NF with a 4-card major and longer diamonds, 1C-1D-1NT-2D as game forcing with 4 hearts and longer diamonds, 2H as FG with spades, and 2S as a relay to 2NT either to sign off in 3C or various other game forcing hands.)
I can't answer your other XYZ questions, I've never played it.

Frances, you just described xyNT (after 1x : 1y : 1NT, 2♣ forces 2♦ to play or invite, 2♦ is GF. XYZ uses 2m the same way after any 1x : 1y : 1z)
