How about:
1♣: 15-17 Bal or ♣s unbalanced, could have longer major if less than 18, non-forcing but can have near game force values.
1♦: ♦s unbalanced, could have longer major (if ♥s, 14/15-17) if less than 18, non-forcing but can have near game force values.
1♥: Strong artificial, either any game force or balanced 18+ Bal or 18+ with a 5cM, or 15-17 with a 6cM or both majors.
1♠: 10-14, 4♠s can have a longer second suit, or 6+♠s.
1NT: 11/12-14, Bal. Can have up to 5♥s but not 5♠s.
2♣: 10-14 5+♠s and 4+♥s (Reverse Lower Flannery)
2♦: 10-14, 4+♦s and 5+♥s
2♥: 10-14 6+♥s
2NT: 21-22 Bal
Rest: Preempts
After 1♥:
1♠: negative without 5+♠s
1NT: balanced or semi-bal positive
2♣: negative with 5+♠s
2♦: unbal positive without a six card major or any 5-5
2♥/2♠: positive with 6+ in other major
2NT+: 5-5+ positives
After 1♥-1♠:
1NT: 18-20
2NT: 23-24
2♣: Both majors, below a GF. Responder assumes 15-18 and opener bids over signoff if stronger. 2♦ asks for best major
2♦: Strong multi - 15-17 with 6+ in a major, or GF major or GF bal
2♥/2♠: 18 to near GF, 5+ major, not 4+ in other major
3X: Natural GF
The structure and the responses are ACBL General Convention Chart legal though your local club TD can ban anything they wish in club games. Edit: this is wrong, the 1♥ bid is not legal under the GCC outline
Strong Heart, anyone?

In the New Zealand Bridge Magazine April-August 2005 Andy Braithwaite wrote a series of articles about using a strong heart opening
The articles discussed the theory behind using this structure and also some of the problems
The basic structure suggested was
1♣ 5+ ♥ 11+ points unbalanced (forcing)
1♦ 5+ ♠ 11+ points unbalanced (forcing)
1♥ 16+ No 5 card major unless balanced
1♠ 11-15 Precision diamond style hand
Higher bids as per what ever form of precision you are playing
The reasons for using this structure were:
(1) Remove the overloading of the 1♣ bid as it can no longer contain a 5 card major. Obstructive bids over the strong opening are now less dangerous as the hand is better defined.
(2) Allow the use of a forcing major bid with an intermediate step availiable to responder. The bidding can go:
1♣ - 1♦ - 1♥ which could show 11-15 with 5+♥
The major problem is that the structure is considered HUM in almost all countries.
Most system regulations will allow using a Strong ♣ and short ♦ but not a strong ♥ and short ♠. Also ACBL land will not allow transfer openings

What is the extra step used for over the 1C,1D bids? (It must be something really good, or you should just move 1H down to 1C and not skip a step with your major suit transfers -- not to be a spoil sport in this strong heart discussion , but just pointing this out as this is apparently a real suggestion for something to play.)

From my reading of the articles the idea is to use the intermediate step as a form of negative
The 1♣ and 1♦ bids are forcing and unlimited so the option to clarify strength will be needed.
The articles do not go much into the followup bidding or structure as they were more about why you may wish to interchange the bids and also the ridiculous situation that doing so would make the System HUM.
One possible structure would be:
After 1♣
1♦ negative 0-8
1♥ GF relay
Higher bids as if opened a 11-15 Precision 1♥
After a 1♦ negative the bidding can be developed in numerous ways to show extra strength. In particular the 1NT rebid is avaliable as the hand is unbalanced.
The suggestions were serious as the intention was to play this system at the New Zealand National trials. Also the Author is a former NZ representitive and also one of the creators of T-REX ( a real system for Non-natural system freaks )

Author of T-REX!!! Can we get him to post some details of the system please -- the only description I have found so far is "If you are (un)lucky, you will encounter a pair playing T-Rex".
Is is a FP system BTW?
