Important detail: A scenario like this wouldn't be accepted as possible into the astrophysics world without a simulation proving that it's possible. People don't become famous for baseless speculations.

This video is close enough to your question to be worth a look.  It shows multiple simulations from various starting points and in my opinion, it's a high quality lecture.  https://www.youtube.com/watch?v=7dRLvSzDHo8   These kind of simulations, to my understanding, require supercomputers.  The calculations required are enormous.

Are there any simulations of the Grand tack?

The [BBC program with Brian Cox "The Planets"](https://www.bbc.co.uk/programmes/p07922lr) involved some description of the [Grand Tack hypothesis](https://en.wikipedia.org/wiki/Grand_tack_hypothesis) to explain the current state of the solar system.

This theory has Jupiter wandering through the solar system causing various orbital disruptions. Are there any computer simulations/CGI videos available to show how Jupiter may have achieved this?
