Playing 3♦ as strictly preemptive makes little sense. What does North do when holding a decent, invitational hand? You can hardly use the 3♥ cue for all invitational and forcing hands.... since it forces to the 4 level, while at the same time aiming (intentionally or otherwise) for 3N any time opener holds a stopper, regardless of how good the contract is.
But, you are stuck with your methods.
4♦is silly.
To my way of thinking, bidding 4 of a minor in a competitive auction is VERY rarely correct.
One useful rule when considering such a bid is: how comfortable will you feel if the opps now bid game in their major?
If you will be uncomfortable, don't do it.
The opps may be bidding game anyway, but your 4♦ bid increases the chances of their doing so, especially at mps.
By bidding 4♦ you announce extra length and that will sometimes allow an overcaller to upgrade with, for example, xxx in your suit: they are now confident of finding ruffing values in dummy.
Furthermore, overcaller may have a borderline decision. He may opt for pass, playing for the plus score and not wishing to push. His partner was under some pressure and may have bid 3♥ on borderline values, not wanting to sell to 3♦. But when you bid 4♦, you give 4♥ two ways to win: it may make or it may be a good save against 4♦ (assuming no double, if red).
So a bid of 4♦ should be discussed between partners: does it suggest saving if responder has a suitable hand (lots of shape, no defence) or does it announce a desire to defend if the opps bid 4♥.
Absent that agreement, don't bid 4♦.
As it is, neither partner really had their bids. South had horrible shape and North had too much defence, given that 3♦ allegedly promised nothing. So 4♥ makes: that is life: sometimes the opps are allowed to have the hand.
