5th ed conversion for "Promises, Promises" characters

Hey everyone, I'll be running Promises, Promises at GenCon this year (since there are very few ArM games every year). Does anyone have 5th edition conversions for the characters in the scenario pre-made so I can save several days of time?

Also, while I am at it, does anyone have any recommendations for running this at a convention or major changes for 5th edition?
