Teleport Object is what Kuro would want here, but even that is only a single object per casting.
To break them in that situation, instead of having them fall from 10+ feet he'd have to teleport them inside the walls of the cockpit but on the side closer to the inside of the cockpit and not the outside of the mecha and that'd require knowing exact specifications of the exact target mecha lol.
Honestly, I just recently noticed a note on teleporting into/onto moving objects on the PFSRD that pretty much could apply to explaining how to get teleporting inside a mecha's cockpit to work.
By the way…
Because ships are constantly in motion, the caster of spells of the teleportation subschool must have line of sight to teleport onto a ship. Otherwise, a caster must scry upon a particular ship first, then immediately teleport to the scryed destination. Any delay in casting means the ship has moved from its scryed location and the spell fails.

Does not necessarily mean we can use such a ruling from probably a 3rd party source, much less PF rather than DnD regardless of how much the systems works together because I think we're not playing a PF game (
) but I did immediately think back on that quote after reading Hugo's posted actions and Os' response referencing that past discussion about teleporting into cockpits.

Edit: Gosh, I need to get back around to making my post and come up with some amazing (but probably terrible attempt at doing so) gloating because Kat is surviving these constant barrages so gloriously.
