I would for one never disturb a gravid or adult female scorpion with scorplings on her back. Never ever.
They wont even leave their burrow (heavy gravid ones seldom do too), so it is not a problem.
As I said, you can take the hard route and risk stress on the females.. resulting in her eating her scorplings, but you will have full control. Or you can just get them a BIG tank and let nature take care of it. You will have very little losses.
Someone here even stated that leaving the scorplings with the mother for a bit longer promotes their growth. I believe this is true.
Just make sure there is an abundance of food available, lots of hide outs and lots of space. I dont see any trouble this way. Androctonus and Parabuthus are considered solitary scorpions too, yet I put all mine together, even with gravid females and not a thing happens!
Ofcourse if there might be a fight and one dies (highly unlikely) it is me who has taken the risk. So I 100% agree with Streettrash Mitchel.
ps. water the spot you want her to give birth to. I wanted my bicolor to give birth close to the glass so I could see stuff and yes, she went for the moist sand and burrowed there exactly where i watered it. This way she can completely separate herself from the other females, they even shut the 'door' (sand) and open it when they are done giving birth. This is from my own observations.
