More skill tags

Just been thinking, with thunderous leap being a detonation skill, there's a bunch of cool stuff you can do with it (none of which I've explored yet tbh) and it made me wonder about how much of a difference it would make to simply add tags to certain skills, like how much of a difference that could make to their utility.

An obvious example is that it might be possible to add the detonation tag to other leap skills, though maybe it makes a bit less sense with leap slam and vaulting impact since they don't have an element? But what if you add an element via a warcry or charged staff?

The above train of thought got me thinking, might it be possible to use some skills to add tags to other skills? Like if you warcry then maybe it can add detonator to leap skills. Also maybe some support skills can add a tag to other skills, so that a skill can gain the fire tag for instance? I guess I've been playing around smith of Kitava and something like that could be interesting to me, but maybe there would be balance issues. But as a concept this seems like something pretty small that could add to the combos that might be possible in the game.
