If the plate cooler is full flow (no bypass) like the Derale and some Hayden units then it behaves like a tube/fin cooler and it is still necessary to add a tstat. Then it would be plumbed like your simplified drawing substituting the O2O for the radiator embedded unit.
A tstat could be used in either case.

I kinda like it. The only concern I would have is that the oil is much hotter than coolant. The ATF could get quite warm before hitting the cooler. I guess the unknown is how much heat hot ATF would extract from the oil through the exchanger. If the cooler is really effective I suppose it could drop the ATF temperature enough that the tranny followed by the exchanger wouldn't overheat the ATF but that would need to be proven.
An added benefit is better engine cooling. The radiator would be slightly more efficient at cooling the coolant and the ATF cooler would also be removing some engine heat acquired through the exchanger.
