Doubling the finasteride does does not double the gain. In fact, it probably will do nothing to your response. In the original Merck studies on finasteride, doses from 0.1 mg to as high as 10 mgs were tested and the results showed that the 1mg dose gave the best overall response. Increasing the dose might increase the risk of side effects.
