If there are performance problems with the conversion on serving or anything like that, of course storing the data in 5.0 is still good enough.
You're answering your own question here: converting the data once and storing it in 5.0 so it's ready-to-serve is of course faster and easier than juggling between 5.0 and 5.1 all the time.
