> fresh ginger instead of powdered

I'd think about this one. Fresh ginger is wonderful in its place but
(a) the grated pieces are larger than the ground powder so some people
may bite into ginger pieces and (b) fresh has more "bite" than powdered,
more suited IMNSHO to savory dishes than sweet. But if you decide you
want to try it anyway, the conventional ratio is 3x as much fresh as dried.

> whipped whipping cream instead of egg whites.

Extremely possible. Beaten egg whites are lighter=tasting while whipped
cream is richer-tasting and a little heavier. You're familiar with your
recipe so you'll need to decide whether the heavier feel would affect
everyone's enjoyment or not.

BTW, when IS Thanksgiving up there?
