If we can generate a CSV transaction with a locktime for an output TXID, and get Vrn to mine a block that spends that transaction before it should be spendable, we should be able to get it to fork away, I think?
Can you provide more info about it? What is Vrn? Does Vertcoin already activated CSV?
Yes, CSV is activated. But the network is still accepting v4 blocks. But if we can generate a CSV transaction, we can make them fork away.
