Well. In principle, yes. It is a matter of wrapping a wire around the trunks (Ideally one wire, for both trunks are you can then also move them n relation to eachother if you know what I mean).
BUT..
- The wire needs to be thick enough to hold the shape
- The wire needs to be pliable enough to not damage the bark
For non-conifers mostly aluminium wire is used. In this case, the thickness probably needs to be just less than half the branch thickness.
Before wiring, gently try and bend the trunks to see how flexible they are. I suspect they are, but it could be older than it looks.
