The way I see it... it's already offset that way... but I don't know how much of that vertical push goes into the crank.
Funnily enough, some readers pointed out Honda's EX-link, which I knew nothing about... which uses almost the exact same multi-link system, only with a continuously moving lower pivot, basically making it an atkinson's engine, with a longer intake stroke achieved mechanically rather than through valve trickery:
(the animation is a bit off, though... in the final Honda prototype, the connecting rod also pushes straight down on the power stroke)
Thinking of covering this one, also, since it was mentioned... but that's going to be a pain in the butt to animate.
