yes it could be implemented. Its just that I am targeting my next
development evvort in the smokeping area to go for a full rewrite
with an all interactive ajax based frontend which will also have
the ability you are looking for ... but this will be some time off
..

as for a short term solution, this should certainly be hackable ...
the cropping javascript can do vertical as well if stroked the
right way.

cheers
