Maybe found an oversight with part 47720

[Henchmen4Hire]

I was playing around with Stud.io and found a parts combo that maybe needs a tweak. (As in the LEGO part needs a real-world tweak, not the the Stud.io program lol)

As you can see, shaving down the disc at the base of the axle, so it's flush with the section right behind it, would let that mudguard piece (and its variants) fit on top of it with just one plate needed between them.

Well...I think it would work anyway lol. Just a suggestion.

Hmm. I don't cut bricks for cosmetic reasons but that's interesting none the less.

Interesting, yes, but what do you need this combination for? I don't think it's an oversight as most of the time it is an unnecessary combination of parts.
You're not using the mudguard as a mudguard, only a structural element, so I don't see why a plate-built alternative wouldn't suffice. 
If you need those two studs positioned in that exact spot above the bracket, you could simply do away with the orange bracket part and build it out of technic bricks and normal plates instead, achieving the axle at the correct height relative to the studs.
