But a "Deal or No Deal" referendum would be pointless, just another example of the UK thinking it's the only player at the table.  The EU's position is basically, "If you want to change your mind, we'll entertain that.  If you don't, the clock is already running, make a proposal."  A "Deal or No Deal" referendum would be seen as nothing but a lame attempt to stave off the deadline, and I don't see the EU being at all interested.
