Okay, I tried it. It became quite clear that to win this will be an absolute tweak fest.
I have a reasonable solution but no way will it be the winning solution. I can see a cheap way around the corner but it explodes 9 out of 10 times when I tweak it and it even tweaks randomly so I'll leave that to the masochistic tweak freaks
Edit: Seems like not only is the cheapest way around the corner a tweak fest, but the cheapest catchers are also a random tweak fest. Shame, I liked the concept of this level but it's not one for me.
