I think that many of the feats from BRCS can be easily adapted to 4e, I think this is good. The feats in BRCS helped make the various groups feel unique.

In addition:

Phalanx Tatics
PreReqs: Heavy Shield Profiency
STR 13 DEX 15
You grant allies adjacent to you a +2 feat bonus to AC.

Racial feats, I think first organizing how we want the race's attributes to come out would be good.

Bloodline, while I like KG's idea, should have their own place in general.
