I have been doing this kind of filter reworking for quite a while and it is truly a good idea. Remember that what you really need is to make enough room for bio filtration not too much carbon inside! One sign that you are overfeeding is a filter that gets clogged very quickly. Good Instructable well done and useful too.

Is there a specific hot glue stick needed (or more specifically to be avoided)? Is it safe for the fish?
How well does it filter compared to the store bought one?

I just tore off my old one and stuffed floss behind it. Its more of a medium for bacteria/whatever to grow on than an actual filter.
