I have had my Circuit for a couple of years now and I have 'personalised'/altered a couple things on it already to lighten it to suit my needs more and have 2 more things to go. 1 is making it a drawstring closure. Easy. The other is a little more difficult and I am asking if anyone had any experience is anything like this type of alteration:

Anyone done this type of alteration or anything like it?
To help describe in pictures, I want to go from this:
