Well, I'd assume RPers in general will realise the reason Roe names look the way they do, so that shouldn't really be an issue.
As for in general, the way I think about it is if the first name has something easily abbreviated to a short nickname (which yours has), it isn't an issue. Might just be in my experience but people very rarely refer to someone by their surname, so that being more of a mouthful is less of an issue.
Then again, if you don't want random people to abbreviate your first name to a short nickname you're pretty much out of luck, because people really like to shorten things.
