It may be possible by using the end of the shot at the end of the film where the Falcon jumps out of the Resistance system, and then there are two possible shots of it falling out of lightspeed, both requiring the removal of a planet.
Okay, that should be possible. I don’t really see the need for the addition though. Would it really make sense to put the ship into lightspeed at that time? They just escaped, and Rey leaves the cockpit to meet up with Finn (I don’t think leaving the controls and just lightspeeding blindly is a good idea) and they haven’t even decided where to go yet. And then they would leave lightspeed without being at the controls, is that even possible? Or does the ship leave lightspeed because of the gas leak?
She does mention at the start of the repair scene that it’s the motivator, which I would assume is the hyperdrive motivator. She then says that if the ‘propulsion tank’ overflows it will flood them with gas. So the ship drops out of Hyperspace because of the sudden leak. Han also leaves the console while at lightspeed, so once you have a course and jump I expect there’s not much risk, at least with a good ship. It’s also established that Rey is no slouch when it comes to the hyperdrive of this particular ship.
It’s a bit of a stretch to think that they would jump without a clear destination, but it’s also a stretch to think that they celebrated before getting out of the system, and then just hung out near Jakku repairing the ship before being found by Han Solo, who was found by two gangs, and none of this appeared on the Finalizer’s radar.
I found a potential source for the Falcon going to lightspeed. Recall that I cut the Falcon’s jump with my Starkiller destruction re-foley, so I could merge that with the end of the escape from Jakku shot:

It would require some blurring and engine glow to the first shot, but it might work.
