Will it work after the Istanbul hard fork?

It will. The gas used by single CREATE2 transaction may increase due to EIP 2026 (https://eips.ethereum.org/EIPS/eip-2026), however this prepayment is refunded upon selfdestruct (i.e. in the same transaction). To be honest, I still do not understand, whether the prepayment is refunded in ether or gas.
