Hi John, BandMerge is usually adopted to create a multiple bands coverage/raster from multiple single band objects. I think that what you actually need is a Mosaic operation instead.
As an instance: https://github.com/geotools/geotools/blob/master/modules/library/coverage/src/main/java/org/geotools/coverage/processing/operation/Mosaic.java Please, let us know if that works for you.
