Anything is possible, but this would be quite hard, as the core operation
is an intersection, which we do not have for geodetics (one also gets into
questions of what precisely to use for chopping, since a "square" isn't a
square, for example. But the proximate problem is the lack of geodetic
intersection.
There are a lot of constructive geometry problems that could be handled in
geography if done in a local gnomonic, but that is of course constrained by
the area of application of the projection, so things would fall apart
against even very simple examples that happened to extend outside the area
of validity.
