Interesting problem - what exactly would an "aggregate" image be?  The
relevant parts side by side, one below the other, as separate layers
in a combined image?  If the latter, what "mode" would you use to
combine them - blend/burn/multiply/as a mask - and what opacities?
Should they be scaled to the same size before combining or not?
Doesn't really fit with the usual map:aggregate/map:part without a ton
of extra info as to how it should be done.

OTOH, something like the include transformer might work better - an
input document describing how the images should be combined, with
:include elements specifying the various other input sources.  But
then you need a pipeline that handles both XML and image data...
Sounds like fun ;-)
