A similar request was posted here, sounds like you were right the first time (field5) :

I'm looking for the same thing, only I want to know how to use conditionals so that if the user leaves the custom name blank it'll default to the registered name. I haven't found any answers on that part yet

Add a new userprofile field

Call it Display Name make it a signle line text box
make sure to note the field id

now,

find in your postbit template $post[musername] and replace it with this

<if condition="$post[fieldX]">$post[fieldx]<else />$post[musername]</if>
replace X with the filed id
That SHOULD do it, altho i dont have the time to look directly at the templates let me know if it works or not
