Big hand opps preempt Bidding problem

Most people use 3♣/3♦ as different types of major oriented two suiters. (The either qualify strength or express a preference between the majors).
I've also seen some treatments in which 4♣ and 4♦ are used a NAMYATS type bids showing (respectively) a strong 4♥ bid and a strong 4♠ bid.
If I had this type of NAMYATS bid available, then I'd consider 4♥ with the hand in question. Lacking this agreement, I'd bid a simple 3♥. (Even with this agreement, I'd probably bid a simple 3♥. Yes, that suit is fantastic, however, I really don't have anything else)

3C (showing a good hand with hearts).
4H is ok as well, and probably best, because,
they cant bid 4C/4D.
With kind regards

We need to allow partner to have a clue as to the nature of our hand, since there is a strong chance that LHO is about to get involved. 3♥ would convey less info about the quality/length of the hand, while arguably suggesting at least a little more defence on average. 4♣ as a namyats bid is an appealing idea, and i will discuss with my regular partners, altho no-one around here plays 2N this way. If it were available, then it is borderline whether to use it: I would not open this hand with namyats... it is just a touch too short of tricks (actually, about .4 of a trick short for me).

Our ultimate goal on defense is to know by trick two or three everyone's hand at the table. -- Mike777
I have come to realise it is futile to expect or hope a regular club game will be run in accordance with the laws. -- Jillybean

If 3♣ shows ♠ also, then what's 4♣? I might bid that...

I have a question for the 4♥ bidders.
1. Do you expect to make the hand, or are you bidding as a sac?
2. If you expect to make the hand, assuming RHO has 13 HCP (the middle of 11-15) that leves 12 HCP for pard and LHO. Lets say they are split 6-6
What 10 tricks will you make? 7♥ + 1♣ = 8
What are the other 2?
If pard has the ♠ king and LHO the ace, thats 1.
Pard may also have wasted values in Dimes, like the Q.
How likely are you to make 4♥?
If < 50%, is it worth bidding 4?
What about 3♥?
Maybe you can set the opps in a part score?

I expect to make.
Tricks for partner?
He's 50% likely (actually slightly above 50% likely) to have a diamond ruff.
For his HCP (not counting jacks)...
K♣, Q♣, A♦, A♠, K♠ should be tricks.
K♦, Q♦, Q♠ should not be tricks.
I expect him to have two of these.
Looks well above 50% to me.

Arclight (obliquely) brings up a couple interesting points:
I ran a very quick sim to see who many tricks this hand will take in a Heart contract
8 tricks 4
9 tricks 13
10 tricks 16
11 tricks 6
12 1
A couple things stood out from the sim
First: The odds of making slam look pretty slim... When I originally suggested a 3♥ bid, I was assuming that the 4♥ jump should show real strength. (Preempts over preempts are strong and I was assuming that the 5-5 hand should be treated as a preempt) My primary concern about the 4♥ bid was not that we'd go down, but rather than partner would get excited and explore for slam with inappropriate hands.
Second: On the hands where we went down, the opponents were typically making game in Spades or 5m
I did a slightly more random sim in which I assigned South 7+ Hearts and 10+ HCP
7 tricks 2
8 tricks 6
9 tricks 11
10 tricks 15
11 tricks 6
12 tricks
The pattern was pretty similar.
Gearing methods towards exploring for slam doesn't look particularly reasonable. I'd like to change my vote to 4♥.
Also, the NAMYATS structure that I like over a preemptive hand with both minors (say 7 - 11 HCP) doesn't look like a winner here.
However, it might be reasonable to differentiate between a raise to 4♥ with good defensive values and purely preemptive raise.
