Yep, that works.

Often times the right answer to solve a problem is to not have it in the
first place, so good call.

Just make sure to handle the failure cases reliably such that at the end
the keypair is removed.  Ie, you do not want to end up with hundreds of
keypairs if you use your program regularly.
