I would open up those junipers to encourage inside growth. It seems a lot of growth is a bit too far out from the trunks. You could open them up, cut back some of the long branches and encourage budding off the trunk and crotches. Then in 2-3 years you may have the makings of some awesome little shohin or slightly larger trees. You'd be surprised what some sun to the inside and fertilizer will do. You can probably also do several airlayers from them at the same time if you are so inclined. Have fun with them.
