Currently, we do not plan to do it.
Something I think should have a bit more thought behind it... It opens the doors for mistakes that are hard to fix in the most part.
@SHaun,
Say you have 3 account types. Red, Blue and yellow.
Create a new user called reduser and make him a red account type, same for the blueuser and yellowuser.
Once you have created these accounts open up phpmyadmin (or however you can to see your database)
Look in the table ow_base_user
Near the end you will see the 3 accounts you created, reduser, blueuser and yellowuser.
In each line you see at the end the account type and a big long number. Each number represents the account type which will be different for red, blue and yellow.
All you need to do is to take a note of the number of the account you want, copy the big number and paste it into the account type area of the user you want to change account types for.
***BACKUP your site and database before you do any work on it.***
