The amount of miss transformation in the OG show is vastly overblown, It happened less then 20 times actually. Even including times where something is activly messing with the watch. Same for AF, it was omniverse where miss transformations where a constant problem.Sure you could get one or two episodes out of it, but that all.

While Lucy stepping into the roll of symbiote suit for Gwen full time works, in a way Ben cannot.

I can see it working better from a action standpoint as well. You have Ben with his transformations. While Lucy can ride Gwen's body, which frees up Gwen to focus more on magic.
