You can create multiple ads within an ad group & run these at the same time. Leave them running for at least a week or until you have enough data to make a decision. This wont harm anything, just make sure to pause the one with the lowest CTR at the end of the trial.
Make sure in your settings you change the ad rotation to rotate evenly so all ads get shown the same amount of time.
