I remove the need for the bonus action for characters with the two weapon fighting style.
I want it to cost a bonus action for rogues, because having a second chance to land a sneak attack is well worth the opportunity cost of not being able to use cunning action.
But for warriors who want to dual wield, the opportunity cost is generally too high, IMO, which is why I apply it to the fighting style. (A rogue who dips to get the fighting style pays their opportunity cost in a delayed sneak attack progression.)
I'm not so sure about the idea of combining the damage. With the Dual Wielder feat you essentially deal better than two handed weapon damage (2d8). If they can somehow add bonus damage on top of that (dual wielding flametongues) the damage could get completely out of control. I suppose that you could just avoid giving out more than one flametongue in a campaign, but IIRC there are spells that add elemental damage dice to your weapons. It seems like it has the potential for abuse (though I suppose if your players aren't the sort to do such a thing, you're fine).
