I have two similar trays in my Revo loosely zip tied together to hold my misc. stuff (food, rope, fishing tackle trays, even holds my travel coffee mug - always nice to enjoy some hot coffee and a croissant while peddeling out to the fishing areas)
by having them loosely zip tied together, my center bucket fits just fine if I slide the trays off center a few inches. One can shave or cut the sides of the trays down a half inch or so if necessary for a better fit for the Hobie bucket.
Bob - nothing wrong with taking a magic marker and labeling the lids of your tupperware -
I have a larger Tupperware container in my front hatch to hold my battery, dry bag, fish finder etc. when not installed - not too hard to get in there and once it's in, keeps stuff from sliding around
