and what is the problem? download that skin, see what font it uses to write the player name and repeat it in your player overview panel
will be something like
<widget class="person_button" id="name" alignment="left,centre,can_scale" size="large" font="signature" colour="text" display_format="2">
<record id="object_property">
<integer id="get_property" value="dref"/>
</record>
</widget>
and in the directory, ./font create a signature.fontxml file like
<record>
<string id="file_name" value="your_font.ttf"/>
</record>
and copy the font to the same directory
"signature" is not magic, it is just a font that is difficult to read
