Why stop with the radiator?  Move the oil cooler there as well to make this approach worth all the effort.  And there will be a lot of effort : )

Quite correct Tracy,
Nearly everyones favorite example the P-51 used stacked radiator and oil coolers. My thought is if you go to the trouble of a wing mount or belly scoop run a slightly larger radiator and one of the large fluidyne water to oil coolers. (much to P.L's chagrin) Many nascar teams do use them. Mark Stetle (sic) put one on his 20B powered Lancair and it has helped his climb cooling a lot. His is a Lancair ES 4 place and seems to be cooling very well now.

Bill,
 Can't remember who - but the suggestion of an air cooler before the water to oil cooler is a good one. Would certainly stop any possibility of oil over heating the water and have the added benefit of the water heating the oil.
