Should be okay, unless you have a truly tiny machine. You don't have to slavishly follow Norbert's published design, you could simplify it quite a bit. A couple of latching points would be sufficient, and you can make these separate from the rest of the assembly if you choose.
The item he shows is a little tricky to machine, as you can't make it to fit, you have to make it to size, and hope it's right. I believe the commercial item uses a CNC machine to make the parts, which makes life easier in this regard.
Personally I'm not a huge fan of bayonet latching. It does look very swish, and of course eliminates the need for additional securing devices, but they seem like a bit of a fiddle at the pondside.
