In order for that container and the enclosed or on top litter, to score (in a scored container), it must be on a tote to be in the marked level 1 on the backstop. There currently certainly appears to be no rule against recycling the litter in that specific manner. Notice also a human player field introduced bin first on the floor, then a container stacked on top of that, then human player feeds the litter into the container, then lift the whole shebang very carefully now from the bottom up bin, right up and onto a 4 bin stack...Topped off. (The turn around and drive forward is the trickiest part without dumping that container into all those nicely stacked bins).
If you attempt to recycle litter into a container standing upright on a five grey bin stack without throwing it into it, you will get called for going over a robot height rule for sure. Now, if that Container is laying horizontally on top of a 5 bin stack, you could do so without exceeding that height limitation, but you may be playing w/ fire there too when you cause that container to roll off possibly knocking down your whole stack among possibly other things like crushing your own or alliance partners robots.
TNA under the existing rules will still be a major issue though.
