you cannot do both practice togeather. You have to chose for one profession. Others are the degrees only which you can write with your name in visiting cards and in your profile.
I also agree with Tilak ji that you have to chose for one profession.
But on the contrary i would like to say one thing still you can do both practice together in a different way. Let me clarify if you take COP for CA then you can not sigh/certified documents which is required to be sigh/certified by a practicing CS but still you can provide your consultancy on various corporate law matters like Incorporation of company etc.
In short you can still use your CA/CS skills even if you adopt any one of the profession as your carrier.
