Halfling Helpful racial trait and Cavalier Order of the Dragon compatibility

[Gherrick]

Helpful (Halfling)
Benefit: Whenever you successfully perform an aid another action, you grant your ally a +4 bonus instead of the normal +2.

Aid Allies (Ex)
At 2nd level, whenever an order of the dragon cavalier uses the aid another action to assist one of his allies, the ally receives a +3 bonus to his armor class, attack roll, saving throw, or skill check. At 8th level, and every six levels thereafter, this bonus increases by an additional +1.

Is there a way to get these to stack legitimately? I'm guessing not, but perhaps I'm missing something.

[Hebitsuikaza]

The way they are written, no they wouldn't stack. You would just use the better bonus.

If you are a DM or your DM decides not to play strictly by the rules, but rather by the intention, then maybe one could allow this combination to get away with giving the allies a +5 to categories that the Aid Allies ability covers and a +4 under other circumstances.

But, again, that wouldn't be strictly following the rules as written.
