Oil to water coolers are not uncommon and for their size very efficient. I don't see how it much matters if you're asking the radiator to shed the heat directly or putting an oil to air cooler in front of the radiator and asking the radiator to make do with hotter air but less heat.
An advantage of the oil to water cooler is much more stable oil temps, albiet sometimes higher temps.
