How would it be messy and complex? If the silver/gold coin thing dosnt go ahead just send out the fund to the original stake holders just as they did with genesis block
People who failed to redeem coming out of the woodwork again. People who don't have access to their stake address any more having a moan.
I don't think it sends a very forward looking message but I certainly wouldn't object all the same. Original stakeholders should be legends of the past.
