well, i know my english is not perfect but i think i am understandable.

you're saying 5 nodes will be hardcoded.

i'm saying that chains on that 5 node will be different... they are different now.
that 5 node will continue to fork each other.

i think :
you need to leave only 1 hardcoded node in wallet.
delete chains on other nodes
re download chain to remaining 4 node from hardcoded one
