I suspect that undeveloped queens; the "princesses" if you will, look similar to the workers until it is time to take on the mantle of breeding queen, when they balloon.
I'm sure Lorne had something planned for that eventuality. I imagine that she would have given life a little more time to prove itself when the option of escae presented itself to her. Perhaps a huge bird portal would open up beneath her, though that seems too easy. I expect it would have been more like a total raid, with freed and native mudokons dropping out of portals all over the labs, geared up and ready for action, protecting Abe, Munch and Sam as they make their laborious escape. The fuzzles may well have leant a hand (so to speak) and several airships would probably fly out to prevent Abe/Lulu's airship from getting away, in the biggest Oddworld battle this side of Hand of Odd.
At least, that's what I hope it would have been like.
