As you have just made this combo, and look like you like making stuff, can I make a couple of suggestions.
One thing I always do to my Zebra billies is to add a 'lock' for the handle. This makes them easy to use, and also means you can pour water/food from the billy while only holding the handle, so there is no need for gloves or other implements.
I have tried to take a pic of a handle lock, but as my billy is a well used one (for that read: dirty lol), I am not sure how well it will show.
This is in the locked position:
This is unlocked, so the handle can fold for storage:
The locks are made from either old issue hexi stoves (nice steel) or from tin cans.
This is a rough idea of their design:
Its a bit like a capital 'T' with the lower leg rolled over, so it slides between the pot and handle nicely, the the top right arm folds around the handle, followed by a double fold of the left arm around the handle. You could JB weld or solder them together, but I have never bothered and have not had any issues.
As for using hexi with a pepsi/coke can stove. I would only ever turn the stove upside down and use its concave base. I would leave the top clear though, as this leaves the perfect space to put a tea light. This can be used for lighting (no surprises there) or for fire lighting etc. You can even use a citronella tea light for getting rid of insects.
If you do prefer the mesh option, then you can always 'mirror polish' the base of your stove, so it can be used like a magnifying glass for fire lighting (or just to provide a funny reflection of you for amusement lol).
Just a few ideas, but the handle lock makes a big difference.
