Can late model stubaxles be fitted to early model suspension

[ozzi_in_the_uk]

I am looking to do a big brake conversion at some point, and unfortunatley I have the early model front suspension setup. And all the Audi ATE 57 caliper mounting kits avaliabe all require the late model uprights, as they have the narrower disc hubs (if you know what I mean?).

So does anybody know whether I can just effectively fit the later stubaxles (uprights) to my early model lower control arm, without causing any concerning steering or suspension issues?
