Not successfully (AFIK).  Those are usually much too small to transfer the 1/3 of the cooling load that oil cooling represents in a rotary.   The oil to water coolers that have worked are pretty massive.

Tracy,

Has anyone used a radiator with an integrated oil cooler?

Well the basic idea has validity because I carried it to an extream.  My rad is inclined about 80 degrees to the 5" duct so flow axis is almost perpendicular to the duct.  A 5" rad would never cool that 20B so inclining it radically was the only answer in my configuration.  Water cooling has never been my problem.  Oil cooling is working pretty good with the new oil cooler.  It was the "30 row oil cooler" from CXracing if anyone is curious.
