Okay to stick a SRAM GXP crankset straight into a Shimano bottom bracket?

Shimano bearings are 24mm dia.
Sram are 24 DS, 22 NDS
You'll need either a reducer for 1 side, or if canyon are running BB86 now, a GXP version of that

Need a wavy spacer to make it work on the non-drive side.

I was thinking more like this:

Ok I'm not a great source for bike building knowledge but that was what I hunted down on ebay when I tried to use sram gxp on my Madone BB90. Let's wait for other replies for confirmation! [emoji1]

Yeah it's definitely press fit BB86. So wavy washer and the eBay spacer and sorted?
The GXP axle clamps onto the left side bearing, this is why you don't need a wavy washer - there's no side play. The image above doesn't show a GXP axle.
The converter will work for Hope BBs, but I don't know what the inside of youe PF BB86 looks like, and how wide it is. Both parameters need to be very close to the Hope specs for the adapter to work.
I know what I'm talking about, I'm running Red GXP cranks in Shimano BBs (BSA though) on 2 bikes, and it took some time and modding until I found a solution that worked reliably for me.
Your best bet is to get a SRAM BB.
