Would we be able to predict and observe gas giants in our solar system 'capturing' a comet or asteroid as a moon if it were to happen in our lifetime?

We use planets' gravity to slingshot probes and spacecraft and increase their speed. Would it be possible to slingshot back and forth between the moon and earth for example or two much larger bodies so as to potentially double this speed or is it capped by gravitational (or other) constraints?
