90 Degree turn while slipping

I can't find anything in my books about how to make a 90 degree turn
(e.g., downwind to base) while in a full slip, but maybe that's
because it's so obvious. (Given my limited # hours, just because
something seems obvious to me doesn't mean I'm not going to check it
out.) I figure I'll turn with roll input, but can't picture the side
effects from doing that. If I know the side effects I can have a
chance of being ahead of the plane during the maneuver.

Anyway, is there going to be any adverse yaw from turning in this
mode? Even if there is, I don't think I can do anything about it,
but enquiring minds want to know. The other question is if the
attitude going to change as a side effect of the roll input. This
will be in a 2-33.

Thanks
