I think its actually a great idea! One it would be cool to be able to change the melee weapons of some. Like say titans get a arc battleaxe or crazy light sword, and the warlocks could summon a sword and could choose to use it as a melee or as range like the throwing knife, and the hunter could change their knife to a katana or machete. Two because it would add to customization, combat, and character diversity having them each have their own type of melee weapons.
