The ideal of mimicing a backboard as a way of recieving cross fields passes occured to me.
1) I think you might not be considered to be violating R08c, if you had a way to only show the backboard when you were attempting to recieve a pass.
2) I am not sure that a random robot (your teammates) vision system would be able to lock on to a backboard in front of a background of other backboards.

Perhaps a better idea is to come up with a secondary vision target that will not interfere with robots shooting hoops, and get other to accept it, mostly by sharing the code that will work with that target design.

It certianly is a way of enabling cooperation between teams that is in the sprit of FIRST.
