And not until the autumn when the sap has dropped back down. Could you not plant out in the garden and allow to grow naturally?

Yes you can but be very careful to keep it balanced and symetrical.Whatever you cut back it will take some time to grow again and Acers should only be pruned back if it really necessary.
