Your plumbing work looks good - especially having done it for the first time. I can also appreciate your hard plumbing and how you had a color scheme going on.
Everyone will have their own preference to how they want to run it. Some good ideas here and you'll just need to see what works for you - you have to live with it not us LOL. Personally, I would just raise the filter socks and not bother with more mechanical. You can find a way to raise the socks either with hook, egg crate, create an acrylic bracket or buy one if you must. This will raise the sock level and you'll avoid detritus overflowing. Make the sock more efficient, and you don't need to worry about more pads - just more work in the end AND you'll still need to swap socks anyway. But again, that's just me.
