Baby Name Poll

We have a 7 year old Summer and a 19 month old boy River and I’m due in 3 months. If it’s a boy we want to get away from the nature thing as it was not intentional and we’ve gotten a few looks. So we like Rowan and think it would be cool to have 2 little boys with the same letter. The problem is since we really don’t want the kids teased, is Rowan a bad idea as then the kids names backwards could form a stupid sentence namely: Rowan down the River in th Summer. Please help as we really want this name but don’t want to regret it later. The similar name Roman cannot be used for certain reasons that would take too long to explain. Thanks for helping.
