There may be a way around it though. Not knowing things by heart it may be iffy rules wise but you could try:
A dragon mag months had polearms and feats, reproduced in Dragon Annual 1 (which is what 5 years old now?). One allowed you to use the other end of a polearm as a bludgeoning weapon.
Strongarm bracers in the Magic Item compendium allows the use of a weapon as if you are one size category larger.
I believe that Mouseferatu wrote the feats.
