Custom Profile Field for Username HTML Mark Up

[DaveNGU]

Anyone got an idea for how I could use a custom profile field to override the HTML mark-up of the username? I tried wrapping it with a div with an !important; but that didn't work.

Obviously we could use {vb:raw username} instead of {vb:raw musername} and do several conditionals for each usergroup etc. and then ones for the custom profile fields, but thats just too much.

Edit: Just realised I was a little unclear. I want to use several conditionals referencing a custom profile field so users can select the colour of their username.
