Is there a typo in your subject line, or are you really suggesting that you want two chain rings the same size?
Edit: Your edit makes a lot more sense. ;)
And from my knowledge, it should be no problem but a couple of potential small steps aside from replacing rings.
Replace rings, add links to chain (if needed), raise/adjust front derailleur.
The need to add links to the chain should be checked the same way as it is checked for installing a new chain. Adjusting the front derailleur is also a standard procedure.
See the usual sites for that info, ParkTool.com, SheldonBrown.com, etc.

You also need to be able to remove the driveside crank to get to the small chainring. You can usually reach the outer two without removing it.
