12 Speed Chain on 11 Speed 1x groupset?

Has anyone tried a 12 speed Eagle chain on their 11 speed Sram 1x road group?  (I have Rival 1).  

I would like to try it as evidently Eagle chains have developed a positive reputation for lasting much longer than Sram's previous 11 speed chains.  I burn through 11 speed chains decently quick.

Also, I figure shifting performance and drivetrain noise may improve, similar to how lots of people use 11 speed chains on their 10 speed groups.  

Sram says its "unsupported" in their tech docs, but I assume that basically means they just have not tested it.  

Anyone have any perspective?

I have a Force 1 rear derailer, sunrace cassette, wolftooth chainring and Wippermann Connex chain. 
Silent. And smooth as butter. 

Pc 1170 chain, Sunrace 11-40 cassette, and 42T Force chainring is not as quiet but it’s not bad.

I run a PC 1170 on my old rival 10 speed with a Sunrace cassette and red chain rings. It is quiet and shifts perfectly.

Mine is a full Rival 1 groupset and i'm really unhappy with it. (I've also had little issues like having to glue in a rattling part in the left lever that SRAM left there when they gutted the shifter, or the hoods tearing up after like 2-3 months where the lever pushes it out). I've made a thread about it a while ago and we couldn't figure out what was wrong with my setup. But I still haven't tried another bike with SRAM Apex 1/Rival 1/Force 1 so I can't compare it with anything else, and I still don't know what silent or quiet means to other people. 

The only thing I know is that the 1x10 on my other bike that i've built from a mix of Deore, ZEE and XT components shifts much better and runs quieter. Which is pretty sad considering how much cheaper that setup is and it's also pretty "outdated" by now.

"A few comments about the AXS chain. The rollers are only .006 inch larger than the standard bike chain, which follows a #41 drive chain design. The AXS chain follows a #40 drive chain design. The standard sprocket design for a fixed drive sprocket is related to the roller radius, but the roller radius is only listed as a maximum diameter - .306 for a #41 chain and .3125 for a #40 chain.

While the sprocket design standard defines the nominal sprocket radius, based on the maximum roller radius, it does not specify a tolerance for the radius that's stamped or machined to create the sprocket. The tolerance has to be plus some amount and minus nothing, if the sprocket is too accomodate a maxium size roller. No one knows what tolerances are applied by the manufacturer. I suspect that the only difference, is a small change to the contact point between the chain roller and the sprocket.

The result is that all the warnings about damaged parts and fast wear are largely unfounded. I put an AXS chain on a brand new Campy Chorus drive train and can't see any sign of any problem after about 350 miles of use. The black hard anodized chainrings still look like new and I see no signs of anything unusual at the sprockets either. FWIW, the AXS chain is quieter and shifts perfectly. I would be surprised if it lasts as long as a Campy 12 chain, but SRAM says the AXS should last longer than any of their other chains.

Here's a link to the sprocket design standard. I can tell you for sure that bike sprockets and chainrings only follow this design loosely. To make both capable of shifting properly, there are many changes made to the shape of the teeth, but of course they have to work with the 1/2 inch pitch chains.
