Just because these trees will never compliment each other doesn't mean they have no value. As individuals, they are very individual, and that gives you a leg up on "doing something different" with them. Watching people try to create square pegs when they have perfectly good round holes will always be the bane of bonsai. I have witnessed professional demos where a straight tree is bent at a 45° just to prove he could. And other demos where a crooked tree is straightened out, just to prove he could. That instilled in me my philosophy of making the best with the stock I have, and pointedly never trying to force a candidate into some preconceived form, just because I was too stupid, or lazy to shop for what suited my goal.
What you have is flexible within limits. You have three separate trees and could make 2 cascade/semi-cascade, 3 wind-swept, or 3 irregular uprights. That's 8 possibilities which you can have any three of as separate trees. All of these choices are not obtainable by someone with straight sticks. Separate these, take each one by itself, and ask yourself, "How can I accentuate what I have to start with here?"
You can have a free-for-all with these and wind-up with three very interesting creations. Go for that! Want a group or a forest? Shop for good prospects.
