I think some formatting changes mentioned here would be useful. What comes to mind most readily is the formatting used in Roll20, but most of the ideas I'm seeing floated would work.
Regarding spells themselves (and this goes beyond formatting and into design) I would personally both more up-scaling, and up-scaling that continues the theme but in a new way. So revivify, raise dead, and the big super raise dead are all one spell cast at different levels, for example.
On that same theme, magic-users who build their spell-lists around themes/domains/tags would be interesting... While the effect can be marvelous reproduced via players choosing to restrain themselves, it can open up design space.
