I've looked it over. There's a lot there, and while it may streamline the process a bit, it seems to me like it overcomplicates combat a bit.
Plus, the way it's written, it almost sounds like you have to take three actions to make an attack with a spell that has a casting time of 1 standard action, like Scorching Ray...and if you have to roll multiple attacks separately for a spell, then it almost seems like it's an action spent for each attack.

Cast a Standard-Action Spell (Complex; 2 Acts): You cast a spell with a casting time of 1 standard action. This isn't an attack action, even if the spell requires a ranged attack roll. If you provoke attacks of opportunity when casting the spell, you don't provoke attacks a second time when making the ranged attack roll.
That's a little ridiculous to me. I may be looking at it wrong, but at first glance, that's what it looks like, and that can really hurt a caster.
I'll give it a try, and let you know what I think after running through a combat with them...but looking over them again, I'm not sure I like them too much.
