I would think they'd be a vast overkill.
The 500R Pot is dissipating all of 80mW end-to-end and the other one around 25. If the Voltage was only across 10% of the Track, which it never will be a 1 Watt Pot should be adequate.
They would have used WW Pots back in the day because they were more accurate and wear-resistant.
2 Watt Cermets would be fine, and I wouldn't worry about using 47R and 1500R.
