Have a look at using concrete posts designed to hold washing lines. They have ready drilled holes through which you can stretch wires at intervals to support your clems. They'd need concreting in for strength and permanence.
Failing that, use tall 4" wooden posts concreted in and drill holes thru those for wires.
You can make a simple pergola by putting matching posts opposite each other and then scrwing more posts across them at the top. Join them with more wires to get a tunnel effect.
I find group 2 clems can be treated as group 3s which makes pruning and combining them easier. Just make sure they are all buried deeper than they were in their pots and feed them generously every spring after pruning them back and pulling off all the old wood. This way you will also reduce the potential weight of your clematis and they will all flower over the summer months.
Arabella is not a self clinging clem and can be sprawled - with guidance - thru a shrub or allowed to flop about as ground cover or down a slope or wall.
