I don't think it would have been a problem. The 'Destiny Swap' only worked when the spell was cast within range of the Elements and it looks like that the Elements, prior to Celestia and Luna using them to defeat Discord, had no Bearer.

The timeline is hazy but I suspect that Star Swirl's time was a long time, maybe centuries, before Discord's reign.
