Which Events are Covered in All Four Gospel Accounts?

I have in mind to make two unified Gospel accounts as a project to help me focus on the essential aspects of the Life, Ministry,and Atonement of Jesus Christ. For the first, I want to draw from events covered in 2 or more of the Gospel accounts. And in the second those found in all four Gospels. Once the information is in hand the idea is to use the most detailed account of an event and add any omitted details from the other accounts to fill in the full picture of what happened, and in what context. Also any recommendations as to what translation/s to use would be helpful. My current list of candidate translations are: KJV, RSV(or ASV), NASB, NRSV & NIV. The first two are (in the U.S.) public domain translations so wouldn't be a challenge if interest developed in others receiving a copy. Whereas the last two are more up to date in the textual research behind them; but are under copyright. Thank you for any helpful information or suggestions you may provide.
