Why does a 3.0 have two oil coolers?

I'm trying to find a way to fit some oversized oil temp/pressure sensors into my 3.0SC motor and stumbled across a post showing the 964 oil pressure/temperature console.

"Man, that'd be perfect!"

...Except it takes the place of the OEM thermostat. Which makes me think the 3.6s don't HAVE a thermostat there. Checking it out and... Sure enough, looks like they removed the engine oil cooler entirely, relying instead on the front fender cooler. So why does my 3.0SC, which has a fender cooler, still have the engine oil cooler from the earlier models? Can I remove the in-engine thermostat and swap over to a 964-style setup so I can have that valley for my sensors? It looks to me that if I just plugged the engine oil cooler lines (something like this and I wouldn't even need to tap...) and yanked the thermostat, I could rely on the fender cooler for all oil cooling, no?



(...Also replacing the "auxiliary cooler loop" with a proper rad/fan a la 993)

Or am I massively overthinking/overspending this, and there's an easy and obvious solution I'm missing?
