Can't resit to the temptation to said that org.geotools.image.mosaic package
(still under development) doesn't make this assumption :). It requires that:
* the ratio between different resolutions are integers;
* if images have a rotation (because it accepts rotated images), all
images have the same rotation angle.
Apart for those requirements it accepts heteregenous overview sets, the image
doesn't need to have the same size, etc. However it still in development and all
functionalities are not yet there. It is definitively not ready for GeoServer
for instance...
My intend is to propose org.geotools.image.mosaic as the underlying engine
behind "imagemosaic" when it will be ready. It works at a lower level (the
former works at ImageReader level, while the later works at GridCoverage2DReader
level). In the main time it may be good enough for some simple experimentations,
but not yet for the more general usage - I'm not sure it would work in your case
without additional code (planed, but not yet done).
