Excellent bag for your purpose.  Two suggestions.  Make sure you have a GOOD bag for the kettle if you are going to use Esbit tabs - very sticky black crud that rubs off on everything else.  
If you want to go lighter, a Ti  pot/cup (I use a Snow Peak 700) over a lighter bottle will reduce some weight and in either case you don't need both the cup and kettle.  Thanks to the crew here for the knowledge, I had the Snow Peak for over a year (got in a trade) but did not think to try it over a bottle.   I carry both, but I am not weight challenged like you are (my weight challenge is not so much what I can carry!  :-). 
The best,

Thanks Jerry!
I put a bandana in the kettle for both prefiltering water and for wrapping the sotve after use. A little bag may work better.  
This pack is going to a platform for a new more robust dayhike kit as I start putting the miles back on. The older I get the  ore I lean towards to a more minimalist and bushcrafty set-up. I'm sure it won't be long before I tweak it again, and going lighter will be on the To Do list. 
FWIW, I've got my eye on making some leather puches while I'm on maternity leave. I'd like a couple for my fire and food kits.
