AG : I wouldn't. Barring very good reasons to the contrary, the simplest 
explanation is that declarer believes, in all good faith, that he is 
playing a trump contract.
I've seen this case at least twice. In both cases, at least one defender 
exclaimed "do WHAT ?", solving the problem in a non-academic way before 
it's too late.
Now there is a debate whether declarer has named an inexistent card (no 
penalty) or whether he's called for the suit on dummy's right (either 
card stands as played or unestablished revoke). A majority oin blml said 
it's the former.
Furthermore, in this case, dummy will probably be bamboozled by the 
instruction, and play nothing, hence no problem.
