well like my edit points out, your suggestion has less to do with controls and more to do with changing the core movement gameplay. if you're thinking along the lines of using silk like spiderman, you're going to run into problems. once you realize the movement has a different flow, it'll come more naturally.
you've got to be attached to something to set your silk so plan your movements with that in mind. maybe think about it in steps - jump, land, silk; jump, land, silk. think of yourself more like a spider or something, rather than spider-man or bionic commando.
