Bryan,
This is very similar to *CoinVault - Secure Depository and Secure Exchange*
technologies that I have shared with you all.

Hi,
One of the biggest problems with the vault scheme (besides all of the
setup data that has to be stored for a long time) is an attacker that
silently steals the hot wallet private key and waits for the vault's
owner to make a delayed-spend transaction to initiate a withdrawal
from the vault.

require any soft-forks or other software upgrades, although it could benefit
from SIGHASH_NOINPUT which I'll describe later.
I call them pre-signed vaults.
