Reverses can be played either as very strong (my preference) or as a very good 16 count or so... maybe some would reverse with AQx KJxx AJ10xx x, but that is not my style.
I don't see any problem in reversing with AQx,KJxx,AJ10xx, x. After all give partner only KJxxx,xxx,Kx,xxx and there is a good play for game. otoh if you exchange opener's black suits, a reverse into 2
♥ is a no-no.
Back to basics: A reverse requires extra strength to cater for partner's possible preference at the 3-level. In the sequence 1
♦-1
♠-2
♥, responder can make weak sign-offs of 2
♠, 2NT (assuming no gadgets here) and 3
♦. It follows that if opener has 6 diamonds and 4 hearts, the strength required to reverse cannot be greater than to jump. So after 1
♦-1
♠, a jump to 3
♦ must NOT be be made holding 4 hearts. This is quite apart from the problem that arises after 1
♦-1
♠-3
♦-3
♥. Where 3
♥ is a no trump probe on a 3 card suit not able to bid 3NT because clubs are not stopped.
As for south actual 15 HCP hand. The singleton K
♠ and not very good playing strength in diamonds make a 2
♥ reverse very pushy. Give partner a hand like Axxx, xxx, Kx, Q10xx and this bid might be the only way to get to a chancy 3NT, but I wouldn't bet on it. So rebid 2
