I am not sure your going light enough and a bit of overkill if it is just mud, a wipe in the grass and maybe a wipe with my cloth if still needed. However, I understand the niceties of having everything in it's place with it's own compartment .
But, lightness is a big thing with me more that I use public transport a lot so anything small and light is an issue but also the weight. I have done the proverbial kitchen sink. Even floats do not escape my lightness regime, 6 floats are all I ever need and no special box for them. If I do not need it they don't go. No spare rod or reel either, I always used the one rod anyway and the reel rarely breaks, I have only had that happen twice in 10 years and that was sea fishing.
One bank stick does me and that is a light one, not a big adjustable thing, just the aluminium 3ft long job. If I need to rest the butt on something it goes on my bag or chair arm or if handy a forked stick found laying around, my knees or lap.
It goes in my bag with barely any weight. if it was just muddy I was worried about I would look to be just having a piece of polythene maybe or maybe a light cotton tea towel and a couple of strips of tape or Velcro to wrap it in which you could still do with two bank-sticks. A tube or bag is still extra weight and something else to carry.
I know it does not seem much but when you add all the unnecessary things up, no matter how light, it does make a difference. It is a regime of mine and would never go back to struggling across muddy fields with a load on my back. I must have carried some things 1000 miles that never saw the light of day.
