You take one wormhole and you accelerate one end while leaving the other alone.
Interesting theoretical scenario but by what means would you get a wormhole to acceleratate and what effect would the means of acceleration have on the stablity of the wormhole?

Just imagine for a moment that wormholes exist. You take one wormhole and you accelerate one end while leaving the other alone
This is precisely the way we turned single wormholes into time machines back in the eighties.
If one objects to this, you can always use two "fixed" wormholes.

Hey, if you're clever enough to make one, you should have no trouble moving it
what effect would the means of acceleration have on the stablity of the wormhole?
Wormhole stability is a big question in itself, before you even start thinking of moving it. You have to prop it open with what we call exotic matter, effectively negative energy density. The Casimir effect is one way of generating this. However, since the time I working on wormholes, we have discovered the universal expansion is accelerating, driven by such a negative energy density.

The same way they did in Stargate SG-1.
