While I'd agree there are better places to mount the oil filter, personally, I've always regarded the hose clamp on the filter body as one of the most ridiculous bits of belt-and-braces design I've seen.
The filter's sealing ring exerts a lot of pressure on its mounting base, and after one or two heat cycles, it is well and truly stuck to it. I still use the original clamp because it's there, but I've never noticed any tendency for the oil filter to work loose on any vehicle I've owned. Usually quite the opposite ...
I rather suspect Norton added the clamp to guard against liability from persons not tightening the filter properly ... though again, most DPOs seem to use as much torque as they can muster on that poor little can ...

Sounds like an improvement. A word of warning to anyone trying it though. The filter head is cast aluminium, and overtightening a taper pipe thread into it could cause cracking... Loctite hydraulic sealant would be a good product to use when screwing the new fittings in, too.
