Erm- Ideally yes, as when dialing in any camber (making TCA longer) you're also dialing in more castor angle by default, so need to make the compression strut longer too, in order to retain the original castor angle with an increase in camber.
Unfortunately on a stock setup you obviously can't do this (you could space the ARB- but I doubt you'd get much real world adjustment, and it's a PITA).
So to answer- yes it can be done on a stage 2, but castor correction is limited by stock ARB.
