I think the spring is much sillier, and would sooner fit Symmetra, who is actually about building odd gadgets from nothing.
A more fitting idea is Bastion have a super-jump. It would have a casting time as Bastion crouches and coils, building up power in its legs, before leaping to a chosen location. Sort of like Reaper’s Shadow Step.
It would be less effective as an attack than Winston’s jump because of the casting time.
