Hi, similar problems here.
To fix the instep problem with Nepals you will need to play around with the positioning of the removable tongue, rather than the lacing alone. My feet are rather different, and I have to position the tongue of my right boot at least half an inch higher than on my left foot, to give some more volume over the middle of the foot. It is a tedious job, as you have to fully open the boot, take out the tongue, press it back onto its velcro attachment, tie the boots again, walk a bit, rinse, repeat...
Other than that, Scarpa boots have a strongly padded heel box that gives excellent support. Here I only have extended experience with the Triolets, but have tried out the Phantoms for a couple of days and liked them very much, will definitely buy a pair when my old Nepals finally die, However, they have to fit well right away, as you cannot really fix your heel by tying down hard, as the padding will put a lot of pressure on your achilles tendon.
