XF 1.5 Custom Field in User Banner?


Is there any way that I could set up a user banner to use a member's entry in a custom field as text? So that if they have a value for (for example) a nickname custom field set as "Boss" then they could have a banner that has a pre-set color scheme but says Boss?

I guess my question is - Is there any way to set up a banner where the text changes on a per user basis? And just doesn't generate a banner if the user does not have any data in the field?
