I know how Grim Harvest works.
With only 2 levels of wizard, you will have 3 1st level long rest spell slots.
No it won't be tricky as to whether or not the Hex damage will actually kill a creature. The solution is to roll the damage separately. You can choose of you want the damage to come before or after by rolling it before or after the melee damage, but you'll have to live with the result. Or your DM could just say no. As a DM, I would just rule no, just because of the intent of the ability vs the nature of the spell. Just to keep it from being an unbalanced, overpowered ability.
sure. but as to overpowered? I don't think healing two to three with a hex would be that much.
I might however go with hex and the invocation maddening hex (I think is the one) that does area damage in effect. I do believe that would work. I would use a lowly 1st level wizard slot for that and surely hex and the invocation would be considered a spell and not a weapon.
I think the general thought so far is its about as good as is its going to get barring a few of the new spells.
I do not think it would do anything with a cantrip however since it says "spell level" unless I am wrong about that.
