Idea after The Bunker Cast Away

Okay, Before I say my idea I'd like to say don't tell me what I already know. I know the Bunker isn't finished and 2.0 and Cast Away wasn't even started but this is just a 4th series I have in mind.

Idea
The Series is called "The Bunker Kingdom", after spending a while on the deserted fighting with with they're enemy's the Bunker decides that they will never win the war without thinking fast. So they gang puts together a time machine but accidentally sends themselves and the teens back in medival time, now they are trapped in medival time so they must finish the war there before Justin Beiber wins another war.

But this is just an idea.
