The shared private key would also be no problem, I would transfer the coins out immediately.
Even a 1=>1 Transaction would be fine if the origin address signs a message of my choice.

Basically just need coins from an aged transaction and the ability to sign a message from that old address.

This makes sense. In the 1 => 1 transaction you could include an OP_RETURN Output with a message stating this. An example:

That would work yes Wink

PMed you more details.
