I thought I saw a number of little sprigs of newish growth on the trunks. Don't remove them.
I would immediately remove the straight trunks, Keep only the trunks that have movement, bends and twists. Keep at most 3, you could go all the way to keeping just one.
Then wire additional bends in the keeper. Let it recover. Oh, never just cut off something, make them into ''jin'', strip off the bark and leave yourself at least half a foot or more of deadwood. You can always cut the deadwood off when it comes to seriously styling a tree. But it is difficult to add deadwood. So with junipers don't ''chop off'' trunks, turn them into deadwood features instead. Once dead, - the deadwood branches are handy for tying guide wires and anchoring wire to when bending other branches.
Then let it grow out a couple years. All the little tufts of green will become branches. let them grow out, use wire to create twists and turns.
I have a juniper that was a boring cutting, no interest. It is in the ''red headed step child'' section of the collection. Meaning it gets ignored and neglected, and when I do pay attention to it, it is only to heap on some abuse. I remove any straight, or boring branch every 2 years, sometimes wire in twist and turns on what is left. Then ignore it for 2 years. take wire off, again remove anything straight and boring. So far this process has been going on for 12 years. Now the trunk has gone from half a pencil diameter to thicker than my thumb. I think sometime soon I'll actually have to think about repotting it and maybe styling it. It was put in an all inorganic, pumice, lava rock and crushed granite mix, and has not been repotted in 10 years.
Point of my example, material that is boring, that you don't know what to do with it, just get rid of the boring stuff, and then let it grow out. Get yourself something interesting to work on while the boring one is growing out. Eventually, it will become interesting.
