I disapprove.
The 5 extra electrum is because you think you have a chance at winning a card for two draws, but then realize you have not won a card. If your last two or first and last cards match, but the other one does not, you will have realized you didn not have a chance of winning a card after seeing the second card. There would be no need for a consolation because your hopes had not gotten as high. Also, people have the good habit of leaving the game once their first two cards on their last spin do not match. They would have to reverse that habit if this idea was implemented.
