Wisteria advice, please

[FigKiller]

Attached are two photos of a wisteria I purchased about 10 years ago; I think it is about 20 years old. It has been neglected dreadfully. It has never flowered. Now I have time to attend to it, I don't now where to start. My only experience with Wisteria is ripping leaders off one in the garden. I never cared what happened to what was left of my 'pruning'. How far back can I prune an 'old' branch without it dying?
This tree is in a 30cm pot and is 80cm from base to highest tip.
I rather like the first photo but the second one shows a rather frightening lean backwards which I'm not sure I can correct by either wiring or tipping forward.
My first thought is to remove the three lowest branches on the right but would there be anything I could do to persuade more branching near the top?
Any advice really appreciated.

You should be able to cut back as based as you like and get new shoots.

Styling sholb thought of as platforms so that the flowers can dangle from and not be obstructed

I liken the second shot and bend the upper section of the trunk out flat, then cut back hard to develop ramification and terMinal branching.
The other branches would also get wired out as flat padsb and cut back as well

Use thick wire to hold the branches and bend slowly you can get lot of movement in wisteria
The first PIC might work as well in real life

Sorry, Ken. I neglected to thank you for your advice. You've really started my rather negligible creative brain working.

My care plan for wisteria is simple.
As Ken says structure is just a platform to display flowers.
Use a good open potting mix, you will not need to repot often because they seem to flower well when slightly potbound.
For me they flower in October, when the flowers are finished remove them and let the tree grow wild.
Lots of water lots of fertilizer.
Late march I cut back very hard leaving only a couple of buds on the new wood. I will wire and remove old wood only if I wish to change the shape.
April repot once every 4 or 5 years.
It is not unusual to wait 10 years for them to begin flowering, then they flower every year.
