Moped / autocycle panniers are suitably cavernous and weight is not an issue: I carry a small bottle of sanitizing hand gel as part of the tool kit - used frequently for hand cleaning after roadside 'maintenance' and theoretically* might act as an alternative lubricant. Drum brakes front and rear means I shouldn't have to worry about lubricating the braking surfaces.
*one of my many unproven theories - as yet untested given to the lack of punctures so far, and if I'm wrong my insurance includes recovering the bike to home...
Could you get the tyre off again though? Less of an issue for you I suppose...
