My only concern is the PC. Is the idea that if it's lost/destroyed your family could still potentially figure the multisig out, maybe with help from a knowledgeable confidant? The only thing I'd add is to thoroughly educate any family who are interested how multisig works. For example your wife could setup a 3/5 so she knows the process and how to spend etc. 10k Bitcoin seems like enough incentive for anyone to want to learn.
