What a lovely garden you have. Plus you are learning a lot about plants that go dormant. I say yes, you can dig up and move the hardy fuchsia but wait until spring to do this. Then in May or when the plant begins to leaf out you can water well the night before,  then dig around the roots and try to pop the plant out of the ground and set it onto a tarp or sheet of cardboard. Drag it to its new home and replant immediately. Then just keep the soil moist as it settles in. Don't' worry if you damage any of the branches. You may just want to cut the fuchsia back by one half to make it easier to manage. Be sure to put a mulch of leaves or straw or bark on top of the fuchsia this fall. A late fall mulch could save the hardy fuchsia if you experience a really cold winter.  Once the fuchsia is gone go ahead and and move the other plants if necessary. I might suggest growing the Acanthus in a pot to raise it up to be better seen. It is a very dramatic plant with those huge variegated leaves. Keep growing, Marianne Binetti
