Oh, are you using my hack as a base of some sort?
If that's so, go ahead. I would even say that if when the time comes for you to upload your hack, you don't want to do an addendum for my version, just create a patch with all you need. That way it would be easier for you, and for others to play it too, as I know that some people kind of ignore hacks because they need another hack for it, lol.
In any case, I did a quick look over the txt file, I personally welcome the idea of adding magic to the classes. Some class skills are not enough to make a class shine, so adding a few spells to make it a more useful character is always good for me, as long as these changes don't make the specialized magic classes less important.
Of course, it sounds overkill to see Wh+Bl 1-8 in so many characters, but looking at the list makes more sense. I think it's fine, it could work, and MP is limited enough.
About stats, I think they're okay too. I kinda wonder if the group Red Mage/Bard/Scholar/Geomancer is a little behind in stats compared to the others.
About enemies, yeah, that's what I ended up doing compared to original HP (At first with an optional patch, then I just decided, "fuck it, enemies are too easy without it").
