Depends on what the "some number" starts at

Yeah. I should have qualified that. The nebulous diamond I like has actually fewer hand types than the 2+ that Meckwell plays. I also hope to gain imps on my other openings.

I am not really sure what the 1C and 1D openings actually show here currently. But for what it is worth I play both 1H and 1S as artificial after 1C - 1D which helps alot if you are willing to give up on showing club-based hands at the 1-level (or show them via 1D)...

1C = 15+ bal, or 15+ nat, or 18+ any
... - 1D = 0-8 any

1H = 18-20 any, or 23+ bal
1S = 18+ 3-suited or any unbal GF
1N = 15-17
2C = 15-17 nat, using the same system as after a 2C opening
2D = Acol 2 in a minor
2M = Acol 2
2N = 21-22 bal
3C = 25-26 bal, 4-5 hearts
3D = 25-26 bal, 4-5 spades
3H = 25-26 bal, no major

Since you want your 1D opening to be 15+, one option would be to take a structure such as above and play 1D = 15-17 any, while 1C is essentially 18+ any. I am not convinced this makes for a good system but it would at least be playable.

The 2m openings have a rather wide range, and sorting this out may be difficult. For example if I have some 12-count with only doubleton in partner's minor it's not real clear how to bid over 2m. Your 1M openings obviously have the same range, but there you have more space to sort things out (and can play 1NT with two balanced hands and less than game values, which is usually a good partial). I'd have to see a good response structure before I'd be really convinced about 2m here.

Here is what I am currently thinking for the 2m bids and their followups. I am open to suggestions on how to improve this.

2♣ = 9-14, 5+ clubs, unbalanced, no good quality 4+ card major
.....2♦ = asking
..........2♥ = 9-11, 4 poor quality hearts
..........2♠ = 9-11, 4 poor quality spades
..........2N = 9-11, 4+ diamonds
..........3♣ = 9-11, 6+ clubs
..........3♦ = 12-14 points
.....2♥ = 15+ points, 5+ hearts, GF
.....2♠ = 15+ points, 5+ spades, GF
.....2N = 15+ points, no 5 card major, GF
