I like your outside the box thinking, but all of your ideas make managing this free contest more time consuming for FBGs so for that reason alone I don't think any of them would be adopted.
Changing the weekly cut to 10% or 15% might be better that 25% for the reasons mentioned by
@BassNBrew but I don't hate the 25%.
@SeniorVBDStudent - I've never made the finals and a couple years back I got cut in week 13 (or whichever is the last week before the finals)... so based on that experience it's much more painful to be cut late.
