I tried something similar with the shield of light (boost shield on any melee hit). It's all fun and game, until you get something nasty, your throwing hammer is on cooldown, and you have no other mean to do some ranged attack.
But my goal with an Adventurer is to play recklessly. And I felt so far to beat nightmare with this approach.
Once I unlock Adventurer again (long story), I'll probably try a build with some wyrmic tree (they give some additional ranged-melee strike option)
My build has range attack covered by distortion. I've put it into test, the main problem is a weak early game, distortion/hammer are both starting weak. Wyrmic tree is a great option, only class that has AOE as far as range 6 scales with weapon attack. I've test Wyrimic + Magic combat, find out that all hits are considered melee attacks, so if your Wing Buffet hits 5 foes in a 6 range cone, it will proc like crazy. And it fits best with dual wield, Dissolve will hit 8 times, Wing Buffet will hit two times, knock back both time, etc. The only problem is useful skills are not in the same tree, you'll probably use a cat point just for one skill.
I got one question for you.... What do you spend your first category points on? You only start with 7.
