Harmony 12 Advanced on a Macbook Air?

Hello all,
I’m working on a series of short (1-4 min), cut-out animations for a client, and my deadline is immediately prior to a monthlong trip overseas. Plan A (of course) is to get it all done before I leave, but I’m contemplating a plan B, in case of edits or calamity. I’m currently running Harmony 12 Advanced on a desktop Mac, but I will only be able to bring my 11" Macbook Air with me on my trip. Is it feasible to edit/compose on my little laptop (with an external hard drive), or will it bog down and/or crash?
