Hey doing this on the ISS is a LOT fore feasible, and it could be a larger payload too. IIRC the Soyuz astronauts know the're in space by dangling a stuffed toy around, replace stuffed toy with a plush Kerbal, and you're set. Although, if anyone manages to get a Kerbal toy to space I'll be mighty impressed regardless where it's headed. - - - Updated - - - Also thought of something. What if other space game communities see us launching a Kerbal to space and immediately start launching their game characters to space as well? then again, that's assuming we get the damn thing to space in first place
