You will rapidly run into stars being too short-lived for planets to cool and evolve life,

From one table I looked at you _might_ be able to go from Sol's G2 to an F8. There's a distinctly non-linear relationship between mass and lifespan on the Main Sequence table. You can't really use stars that are much larger than Sol.
