As a house rule, sure, why not.
Personally, I'm with Elder Basilisk in that the feat is fine as written.
I have a Ftr/Pal who would love to take Quickdraw, but has other, higher priority feats to select from. He also wields a buckler shield so that he can take other actions in the round, such as quaff a potion, move a weapon to the off-hand (to hold, rather than wield), leave a longbow in that hand whilst he draws sword and enters melee, wield a longsword in both hands etc.
There have been occasions where he has dropped a weapon to draw another weapon, and that is tactics to recognise when you can do that without risking loss of the weapon.
I believe Quicksheathe (or equivalent) should be a special ability of certain PrCs, such as Samurai or Kensai, rather than a feat.
