Wouldn't have been cool if....

In New Moon Edward left Bella pregnant and scared of what Charlie would say she ran away from Forks and to Denali where she was going to ask for their help....she could have had twin girls Renesmee and Elizabeth...Bella forming a tight bond with Tanya was changed oleh her just in time...then when her and the girls went to a high school when the girls were full grown they ended up in the same school as the Cullens??? I just thought that would have been a cool twist to the story:)
