Hey there.
While I haven't personally tried it for such a purpose I can say that it is very unlikely to work for this purpose. The only way it functions is if the actor is set as dual wielding, which only gives you two weapon slots by default, meaning you'd need to have used a plugin like EquipCore to get extra weapon slots on top of those two, or you'd need to have had another plugin modify the dual wield equip type to give extra weapon slots.
In either case, this plugin expects only a maximum of two weapons, so it would only ever strike twice, and each hit would ignore the stats of only one of the multiple weapons being wielded, the others would be treated as armor, most likely.
Even if you had someone modify it so that it attacked once for each weapon, instead of hardcoding to twice if dual wielding, there'd still be many other functions and effects that would need to be tweaked to make it work.
I'm not saying it isn't possible to modify it to make it work like that, but it's not something it will do out of the box.
