(Request) 'Top Friends' mod for 3.7

[VeeDubZ]

looking for a MySpace-esque 'Top Friends' mod so members can chose the order of their friends??

I sure wish I had the php knowledge to pull this off as I believe it would become popular.
Anyone know where to start?
I see in the member.php shows
'fetchorder' => 'asc',
in the friends options array.
Is there any way to hook into the member.php or the friends array()?

Would one of these be used?
./member.php
-- member_start
-- member_start_fetch_user
-- member_execute_start
-- member_build_blocks_start
-- member_complete
