Chell can easily return, and I'm sure there are a billion different ways to get a great story out of it.
Out in the field, Chell takes a step forward holding her slightly charred companion cube, and walks off into the distance. And then falls through a hole in the floor, all the way through Aperture Science and down to the depths. Sounds of testing chambers being rebuilt up high above draw your attention to the insane heights and all the movement of panels and crushing panels way up above you.
You come across an abandoned prototype Portal gun, unfortunately the portals don't stay open for very long as they are very unstable. You makeyour way through the guts of ApSci, heading upwards, perhaps to seek out the help of GLaDOS or avoid her altogether. After about an hour of this, you come across a strange whistling sound and you Portal your way towards it until you find a broken panel precariously sitting against a railing, with a Portal in it, air being sucked out really fast as though into a vacuum. And then as you approach it Wheatley comes rocketing through it yelling at you to destroy the panel. It sucks you towards it though but you grab either side of the panel and go tumbling over the side of the railing, back down into the abyss.
Blah blah blah, eventually you make your way back up to some of GLaDOS's old test chambers and make your way through them. Suddenly she notices your presence and instead of organising a welcoming party with cake, she panics. Obviously you're back to KILL her. Oh no that can't be good! So she starts throwing together test chambers in order to keep you busy while she figures out what to do with you. You see she now has a secret, something she doesn't wish to tell Chell, but something which means she doesn't want to kill her. As the game progresses, Chell makes her escape, eventually coming face to face with GLaDOS once more, and just as she's about to kill her again (by puttin her in a lemon), GLaDOS shouts "I AM YOUR MOTHER!" Turns out she couldn't delete Caroline because she IS Caroline. Caroline Johnson, Cave Johnson... Chell Johnson. "You wouldn't kill your own mother would you...?"
Without time to even answer that question, Wheatley burts in, bumbling and apologising to GLaDOS, hilarity ensues etc etc etc... I'm not writing the story for them. But damn it'd be kinda cool if it happened like this.
