I don't find QFE complicated. Actually I've never used it because (a) it's not necessary and (b) it's not available in any of the jurisdictions where I have flown, but I'm sure I could deal with it satisfactorily if I had to.
But why have two systems operating when you only need one? The rest of the world has already figured out that there are some safety considerations here, and that's why they use QNH exclusively below the transition altitude.
And by the way, if you can't fly a circuit on QNH you shouldn't have a licence. I learnt to fly at an airport where the circuit altitude was 2900 feet (airport elevation 1888 feet).
