Bridge with Tichu Cards

It'd be interesting to see if one could play Bridge with Tichu cards. Everyone gets dealt 14 cards. There are 4 suits from Ace to Two (Spades - Swords, Hearts - Stars, Diamonds - Jade, Clubs - Pagode) and 4 special cards (Dog, Dragon, Phoenix and Mahjong).

If you bid a contract you now have to get at least 7 tricks + the level of your contract, so there are again 7 levels of bidding and the scoring/rewards are exactly as in normal contract bridge.
