Usando o sistema de dados nWoD no V20

Eu sou um antigo jogador do cWod que acabou de comprar o Vampire V20. Fiquei surpreso ao ver que o V20 mantinha o antigo sistema de dados em vez de usar o novo.

Lembrete:

In oWoD, the Storyteller sets the difficulty for each roll depending on the circumstances, with the default being a difficulty of 6. A success is a roll of that difficulty or higher (6 or above, on most rolls). A roll of 1 is called a botch. If any number of 1's are rolled, they cancel out a single success. No more than one success can be cancelled out in this way, so critical failures (A botch with zero successes) are relatively rare. The net number of successes determines how well you succeed, with one success meaning that you are barely able and a greater number indicating better achievement. When you get zero net successes (if you get no successes or if your 1s cancel out your successes, or if you get at least one success and more ones than successes), you fail the roll. When you get zero successes and at least one 1, you botch-- a critical and spectacular failure. If you have a specialty in either your attribute or ability that is relevant on the roll, you may reroll all 10s to gain extra successes, and rolls of 1 on these rerolls do not count.

In nWoD, a success is an 8, 9, or 10, and 10s explode. A critical success is made when you get five or more successes. Instead of altering the target number of the roll, difficulty and circumstances increase or reduce the number of dice in the pool. When your dice pool is reduced to zero or less, you get a chance die. You roll the die normally, but only succeed on a ten (which still explodes) and if you get a one you get a critical failure. All other rolls are called simple failures.

Você sabe se é possível jogar o V20 com o novo sistema de dados? Quero dizer apenas substituir o sistema de dificuldade dinâmica (que é estatisticamente falho) pela dificuldade fixa (a dificuldade é expressa pela adição ou remoção de dados e não pela mudança da regra 7+).
