As mentioned by others, a lightweight rear rack with a drybag strapped to the top seems to be a popular option. I tend to have either a small rucksack or large hip pack for stuff I'm likely to want access to during the day. As you've already noted, packing the main bags well in the first place can make a big difference, and unpacking/repacking during the day can be a proper faff.
FWIW, your current set up looks pretty neat.
