Hi, GreenManalishi.
I was playing around with this idea as well. Check out this post.

It will set the classes() to have the spell set for all to the level that a class can first get the spell. For example cleric cHeal at 39 would be available to all classes at 39. I was unable to get to to work but was unaware about modifying the spell_us file. I will try again with that information.
Splose,
I am also interesting in that code for the extra spell slot, thanks in advance.
