We just took the chainrings off an AXS Red Dub crankset and installed on a Quarq BB30 crankarms with 8 bolt spider. All working well. Note that it wasn't the Quarq AXS chainrings, so can't comment on that specifically.

Have you looked carefully at the area right around the crank spindle for damage/crush? Maybe there is enough clearance/taper for them to mate with each other, but I do think I'm correct in stating the old cranks aren't quite the same shape. Look at these side-by-side.

I think there was a misunderstanding with my question.
I'm gonna clarify myself.
So I have bought the new Trek Madone SLR 9 with the new SRAM AXS 12 speed groupset (complete bike => https://www.trekbikes.com/us/en_US/bike ... =red_white)
This bike comes with a regular crankset (no powermeter) and is a GXP spindle version. I think they are gonna call it dub 24?
These GXP versions aren't available yet => will be available in June/July where I live. Just some manufactures like Trek, Pinarello and BMC get some limited quantities at this moment.
Now I wanted to have the Quarq power meter so I asked my shop if the power meter upgrade is already available for the AXS => https://www.quarq.com/product/sram-red- ... -upgrades/
The powermeter upgrades will be, like the GXP spindle, available from June/July where I live.
So my only option I have at this moment is to buy a complete crankset (DUB => bb30) with the powermeter installed => https://www.quarq.com/product/sram-red- ... cranksets/
My question now is, i know the chainrings are direct mount but if I buy the complete DUB (bb30) crankset with the powermeter, can I take off the DM chainrings with the powermeter and install it on my GXP (DUB24) version? Or are the chainrings for DUB (bb30) and GXP (DUB24) different? Or are the cranks arm different?

I understood your question the first time you asked, but others answered with what I assume is correct guidance.

The 8-bolt interface is the same. The power meter chainrings should be interchangeable with any AXS crankset. Any differences like q-factor would be incorporated on the crankarms themselves.

In your case a pedal-powermeter would be the better option

In my case a the dub crankset will cost me the same as the Garmin Vector 3 pedals.
And in my opinion the Vectors are trash.

Has anyone heard anything about whether the Force version of 12 speed AXS will be released next month?

I went with this option too.... got rid of the vectors and got the powermeter. Saved weight too plus back to Shimano cleats!

Side note. Tested at the shop..... the etap AXS range was still working when the rear derailleur and shiftier were at least 60 feet apart..... Nuts...

When we did it there was no fouling on the arms when mounting the rings to the 8 bolt interface. Again, this was not the quarq+rings, it was just rings.

Just for clarity. grover, did you replaced DZero spider with AXS chainring on Quarq BB30 crankarms? Can you make photos?

Yes, removed Dzero. Installed AXS rings. That's the best photo I have.

Did it because the Cannondale SuperX uses an 83mm wide PF30 shell with chainline of 55mm (Cannondale term it 'Ai'). So needed a long spindle crankset version. SRAM apparently are making an Ai dub road crankset for axs but not yet available.

Awesome! For some reasons I don't want to use DUB cranks. One more real option in addition to aftermarket chainrings.

In UK they are showing GXP chainrings as delivery late June.

However, if your LBS phones the distributor and commits to a purchase then units can be flown in. That brings the eta to late April.
