Monks and combat maneuvers

[zmanerism]

I was thinking of a way to make monks strong at combat maneuvers even at higher levels and have two options. This would make the option of a trip or disarm monkey an option. It would be to add either the monks level or 1/2 to combat maneuvers. thoughts on this would be great. The small additional part would to make the greater trip and disarm available as bonus feats.
