It's your money, but those are some crazy expensive bottom bracket adapters from Hambini £155.00 to £195.00 (i.e. $200 to $250). If you want a thread-together bottom bracket solution, check out Wheels Manufacturing options, which cost 1/3 as much ($60-$80) and are very nicely engineered.
Frankly, if your frame is within tolerances, you won't need anything even as fancy (and heavy) as the Wheels Manufacturing option -- nevermind the Hambini option. For instance, I have an inexpensive SRAM PF30 to Shimano BB adapter on my gravel bike, which I've removed and even moved to a second frame (after crashing and destroying the first frame). The first frame was metal with a metal shell. No issues. The second frame was carbon with a carbon bottom bracket shell. No issues. The only thing I used for installation was plain old grease. The adapter doesn't thread together or anything. It's just two lightweight pieces of plastic with a friction fit. The adapter cost $30 and weighs about 30 grams (i.e. way lighter than the thread-together options).
Compare that to the Hambini adapters, which might be well-engineered (?), but cost £155.00 to £195.00 (i.e. $200 to $250). And his bottom brackets weigh double/triple/quadruple what the simple adapters weigh. Frankly, other than getting the "privilege" of purchasing from a Youtube-famous engineer, I don't see any value in it. Especially for a gravel bike (vs. a race machine used by an actual racer where every quarter-of-a-watt drivetrain loss counts).
Again, it is your money, so no skin off my back. Just letting you know about your other options.
