I am going to give Pope Francis a chance to prove himself in this regard but am skeptical.
I wouldn't think he would need a commission for him to understand the basics
1. Don't expect men who are created by God as sexual and emotional beings to be celibate. Although this will never happen in my lifetime I hope the RCC eventually sees this is not how God would want his creations to live
2. Ordain women to broaden the pool of available candidates and bring balance to the priesthood
3. Establish a no tolerance policy around any form of abuse, sexual or otherwise. There is no first chance we move to you a different parish and cover it up and hope you don't do it again. The first time there is a report or suspicion you bring in the civil authorities to conduct a thorough investigation and let the laws of the various lands mete our civil punishment. You can conduct your own investigation but if you find evidence of abuse then defrock immediately.
4. Defrock any bishop, archbishop, cardinal, etc. immediately if it can be determined they even once moved a priest around without reporting it to the authorities and making an independent determination of the allegations and if found true then to immediately remove the priest or whoever from the priesthood.
If they know they will be turned over to the authorities even on the first allegation this will make them think twice before they molest. It may not stop all of them but the civil authorities can then convict them of sex crimes and make them a pariah for the rest of their lives.
