There already is a P&F spin-off. Take Two with Phineas and Ferb. Why does everyone forget about that? Oh, and we need new episodes of it DC - pronto.

Anyway, if I recall, the Fireside Girls spin-off was just something being considered by Disney a long time ago, but nothing's come of it so far. Such a thing would probably come after the current show ends, and that's a lot way off. So we won't see this, if it even comes to fruition, for YEARS.
