The “bump” would mean to rotate, it would need to rotate the whole mass of the bolt/friction etc towards the cam stud; so in theory more delay, I understand your larger surface area twist delay idea… I think; because I have long thought the Johnson bump, was one of the reasons why they used a multiple short surface area lugs “turning” I.e.

Reckon the cam track alteration would be sort of a half / but more – angle; point being, facilitate carrier moving into cam stud, but on return allowing it to rotate clearly. Maybe use your fewer/greater surface area lugs in conjunction with the above; bet there is away, as in 5.56mm it won’t be too far away already probably from working “reckon it is a bit away” but be worth trying… Radial thing works basically as per, and while no gas might not prove to be better; maybe it would at least work enough to prove gas is better, think it has potentional anyway.

Patent says so… At firing, empty case with high pressure inside, first forces the angled lugs to rotate then, cam pin receives motion as trying to transmit to the bolt carrier with a disadvantaged leverage as most of gained momentum being wasted for this job and thereby leaving less momentum to rotating bolt causing to slow its rearward push as causing less friction on contact surfaces at lugs and counter recesses all resulting a soft recoiled bolt and carrier for even more powefull rounds than 9 mm…, Needs near perfect machining and parts control… Seems not suitable for rifle size rounds… IMHO…, Might work with intermediate calibres though.
