I've just bought a dutch kidney mug, USGI pattern lid and 'stove' – it's a close fit but not quite and means the cup sits too low in the stove part – easily fixable by bending a portion of the aluminium and putting the cup in the wrong way round. Doable but not ideal. Have ordered a USGI pattern mug to fit properly as I love the compact nature of it when compared to my crusader mkii set. Dutch cup is very nice though, so may have to fix up a system around it.
