I redid the toolkit, but left away the tyre irons.

I like your cut-off 30 and 24mm stubbies to deal with the rear wheel axle nuts. I've been using a big Crescent wrench for that job, but don't have a ride-along solution yet.
I was thinking of perhaps acquiring one of these combo tire iron / 30mm wrenches.
https://www.walmart.com/ip/Tusk-Aluminum-Tire-Iron-with-Axle-Wrench-30-mm/548885073I already started carrying a 9" tire iron, along with the short 6.5 inchers that came with my kit, after one very frustrating attempt to fix a puncture with just the two shorties, (and that was on a workbench, not at the side of the road). A spare tube and the 9" tire iron are too big to fit into any of the storage areas, so I'm already into saddlebag space.
Another interesting gadget is the Motion Pro T-6 adaptor, which promises to turn a box end wrench into a 3/8" socket drive. This comes in many sizes, but not 30mm.

I can probably manage a 2nd hex ring with a thicker wall to deal with the 24mm. Or I can resign myself to carrying that 10" Crescent wrench, and keep the $40 in my wallet.
I do manage to pack quite a bit of gear into my oval tool kit area, and also take advantage of some space in the electrical box, where spare spark plug, air pressure gauge, spare clutch cable, 3' alligator clip test lead, micro voltmeter, some baling wire, a bit of Scotch Brite, and more, all manage to find room. My tool bag includes a 6" Vise grip, which can do a lot of jobs in a pinch, including serving as a jury rigged control lever. I have extended the service life of my tool bag with a spray of Armor-all every so often. The plasticisers in that stuff really seem to help extend the life of lots of plastic in my life, power cord insulation on power tools being foremost. Keep it off the steel tools when wet though, it will make some rust.
