Titanium Clip-On Windshield?

How about,

https://backpackinglight.com/forums/topic/jetboil-windscreen/

Looks like we’ll need to fabricate one! As much as it weighs, I like the Optimus screen.

look to me that you would need a few types to accommodate the different stove designs

DESCRIPTION

Lightweight, hard anodized aluminium clip-on windshield for use with canister mounted stoves. Increases stove efficiency and substantially reduces gas consumption.

Fits every gas canister according to EN417 and pots with max. diameter 11 cm (4.3 in). Compatible with standard pots and high profile heat exchange pots. Easy packability (fits around the Optimus Terra Weekend HE pot).

Looks like it attaches to the canister

Yes it does and that is why the height and or width of the stove would make a difference.

For example in the photo posted above it should be obvious that any medium to large pot will not fit.

See the 11 cm limit.

That is correct, it was obvious that it said:

and pots with max. diameter 11 cm (4.3 in). 

The same dimension would apply to the stove.

AliExpress offers one that clips onto the stove itself, rather than the fuel canister.

The one on AliExpress is wider at about 13cm (5.1″) so it will take more pots . However I would not put a pot inside there that has less than a cm or so gap all around.
