Monk's need some love, I completely agree. I think this is a reasonable rule, its a very distinctive feature, and it requires a short rest to recover.
So I think its a cool idea.
If you wanted to do anything else with them:
1) More Ki....just more Ki. Like....just more. Seriously, they burn through Ki so quickly, and without ki they are useless.
2) More self-healing. Monks are on the lower end of defense, so they tend to be a healing sponge. Giving them more ability (and lower level) takes some of the burden of healers and lets them defend in a different way.
Frankly I think the tireless ability they just gave the ranger would be a great addition to the monk (I think the tireless ability needs a tone down if your going to give it to them that low a level, but its a cool ability that works differently than high AC or barb's damage resistance).
