Would being able to swap display names in your Jagex account be too niche of a feature?

Jagex doesn't handle display names in the best way at the moment, there are various scripts that snipe rare names instantly and a questionable grey market.

What if a feature existed within the Jagex Account system that let you swap display names with your other characters?

This wouldn't legitimise a name market in the eyes of Jagex but would still allow for people to have the names they want on their characters, safely - if swapping to ironman etc.

What are your thoughts on this?
