The multi-class rule will allow spellcasters to compete with not spell casters in multi-classing.Multiclassing however could be a problem. Multiclassing already allows players to make single class character look like wimps next to there multiclassed compatriots. Bumping up the class abilities essentially making them higher leveled characters (just without the numbers), increases their comparitive abilities even more compared to a single class character. Now, unless you specifically want everyone in your game to be multiclass, I think anyone who chooses a single class is going to feel like they're being penalized.
Here are some examples:
10/10 --> class features as a 15/15 in all other ways it is an 10/10
2/2 --> 3/3
9/1 --> 9/2
7/7/6 --> 13/13/12
4/4/4/4 --> 8/8/8/8
Certain classes should always multi-class just as per the RAW but with this no fix-it PrCs will be required and class features will advance in an ordered fashion that should not out-of-balance the character. Of course their are countless permutations so only time will tell.
Thanks, hope it all works out as well.Anyways, other than that I don't see any problems with your houserules. In fact, it looks like a very fun campaign your preparing. One that I'd probably enjoy myself. Just one other thing though, make sure your players like these rules too.
