Here’s a rough mockup of BB-8 running to the shuttle with Finn and Rose:

The rotoscoping is very rough, and I just threw on some sound effects that I could quickly find, but let me know whether you think the idea could work!
I think/hope that this change combined with the Finn/Rose deleted scene could be enough to cut Phasma fight and BB8 in walker without the scene feeling incomplete. The scene would now have urgency AND resolution.
