Must the Gaming Board Always Decide?

Is it possible a casino can change its blackjack rules  to favor a player even slightly?  Personally I've never felt someone dealt blackjack could possibly win nothing for it.  But that happens with no insurance if the Dealer turns over the Ace with a 10 showing.  Insurance wouldn't apply.  

     What if a random property decided players would win half their bet rather than a push when dealt BJ in that situation?  Must the Gaming Board approve it?  Not as if the casino will go bankrupt.  It doesn't happen that often but just might attract more players.

Tim,

It would cost the casino more than you might think. The situation you describe (player and dealer both have blackjacks, dealer has 10 up so no insurance bet is possible) will come up about once every 800 hands. If the casino pays out an extra half bet every 800 hands, that's 0.06% back to the player. The house edge is small enough as it is. So, no way.
