I hate hate hate the racial discipline idea. It doesn't fit with the existing class abilities at all, and race in general is a matter for PrCs, feats and substitution levels to deal with — not the core design of base classes. Ever.
-shrug- Still, better than giving them their own special discipline as well as the only reason to take Warblade levels.
Besides, the only reason I suggest that is while all three disciplines are focused on excellence in battle, my idea would give the class some added variation.
Of course, since you favor substitution levels, then basically each of those pairings is a 1st level substitution for that race, with no other changes. Boom, done.
