Is this a sound elephant offer? In the following dobutsu shogi position, is Gc3xc2 a bad move?

It's not a sacrifice, it's a trade after 1. Gxc2 G*b3 and taking the elephant on a3 next.

On the other hand, since doubutsu shogi is strongly solved, you can use an engine/tablebase (e.g. https://github.com/fuzxxl/dobutsu) to set up and see the solution anyway. (I haven't done this, though.)
