1.7” diameter won’t be 12oz. The material weighs what it weighs, and US isn’t interested in their cans Scything.
This is the can above- 9” total and 1.55” diameter. 3.5” OTB, 5.5” muzzle forward, a single light coat of spray paint.

Weight is not my primary concern- that’s my trade-off. OAL added length and diameter are my primary concerns, with sound reduction being important too. I do not prefer large diameter cans- I don’t like the view through the scope, they look stupid, and they are more bulky which is annoying- all preferences, not facts.
In general for field/backpacking cans I do not want longer than 6” in front of the muzzle- shorter is better. For range use, or where length and weight doesn’t matter, I am happy to use 9” muzzle forward cans and get the max suppression that I can without going stupid big. I’m going to SBR a bolt rifle to do a 12” barreled 223 and 6ARC and use a 9” muzzle forward can- that’s nearing max suppression, and for sub 400 yards that’s a good trade-off to me.
