I'd suggest it may be much easier to do a quick cut-out into a fresh box rather than spend months trying to manage adapters and migrate them slowly across into a connected hive.
One way to do it would be to use a bee-vac for the bees, then cut the comb out and tie into empty frames, filling the remainder of the space in the new box with foundation.
To get the comb out of the cone a breadknife would be a useful tool to separate the comb away from the cone walls.
As cut-outs go, a traffic cone should be a relatively easy one.
