Flying creature Design

I am working on a project where I need some advice for the wings of the creature

But I have encountered some difficulty in trying to make wing that can double up as a forelimb.

I have consulted a biomechanics guy from a science forum. He said that flying animal size depend on the way they take off. For Example birds have a huge size limit becos they take off with only two legs. But pterosaurs based on new theories take off with all four limbs contributing to the take off thus there size limit is ..... well.

So this is my problem I need the pros here to solve. To design a wing that can be used as a front limb.

Here is the creature I am trying to design. The First one is the ancestral form something like a flying squirrel. The others are my designs, I have no confidence that they can allow the creature to walk or climb trees.
