LE Staves Cast the Dual Casted Version

[NemoTuNovi]

Stupidly simple idea that I'm 90% sure has a reason it hasn't been implemented yet incoming in 3...2...1:

 

A mod that makes it so after you have the dual casting perk of a school, staves of that school use the dual-casting version but are still considered one-handed.

 

Again, I'm sure there's a reason behind it like how it's near impossible to make a new skill tree or some crud, but darn it just seems like such a simple buff.
