Anyway, on topic, one of my friends really liked an idea of having a “gish” that enhances their weapon via alchemy, with alchemical concoctions applied to the striking surface.
Idk if that leads to a swordmage specifically, but IMO it’s pretty good as a potential subclass idea.
I very much just look at it as 'using the weapon as the vehicle for spell application' for a lot of what makes the gish, a gish.
In that line, an Alchemical version makes sense as well.
