The infrastructure to carry out that attack against BCH would cost around a billion dollars in mining equipment and power. Not exactly what you would call a small miner. BCH also has rolling 10 block checkpoints so max you could reorg would be 10 blocks or < 2 hours of transactions. In reality there is nowhere you could rent this hashpower and miners that do have it would never risk the legal, social and monetary consequences to rollback 2 hours of transactions.
