I was re-reading the Ann, and just saw your post ...

A (proven and capable) Developer was contacted , and he would be willing to do the neccessary changes to the wallet.

staking 8% annualy and all coins divided by 1k or 10k

This would require that >51% of the wallets have upgraded with this new wallet before the Fork occurs, less than that number and the Fork fails.
The current exchanges would also have to agree (coinexchange / Novaexchange) , or Sprouts would become untradeable .

Besides of that, this could be done.  Only needs backing from some whales.
