I don't expect it's going to be that easy. But physics is a lot harder to break than mages like to admit.

Trick is, once I settle on a plan, I'll only have time for ONE I'm guessing. I'm good, but even I'm not able to be in two places at once without judicial use of time travel. So whatever we settle on, we have to make sure it's the right one.

Getting in and gumming up the gears will take time and maneuverability. Creating buoyancy rigs will take time and materials. Icing over the water will take time and magical power that I'll have to recruit elsewhere....

Time, time, time. Never enough of it when you need it.
