Interesting decision to rest the cup under the pot. Surely it can get a bit dirty over the time?
My MSR Windburner's cup stacks the same way, but it's less exposed compared to this one.
I also do have a similar setup: Esbit Cookset 585 (- solid fuel burner) + Alpkit Kraku + Sea to Summit X-Mug. Comes to 258g. Slightly smaller volumes, though.
