Request: Spell Damage generate cipher focus mod

Hi can someone craft a mod where Wizard, Druid and Priest damage spells generate focus for ciphers like weapon attacks?

It be useful to combine those classes with cipher then.

Also since most of spells hit in aoe it should probably be something like 25-33% focus per damage point generated as it seems 1 fireball can insta-fill your cipher focus and be pretty broken potentially if focus game is not % based. 

Thanks!
