Since87: I would expect two rads in series (airflow wise) would get roughly 85% of the the single rad air flowrate. Substantially more than 50% in any case. Got backup for your statement?

No math numbers, sorry. I was working on the basis of one of BillA's articles that indicated an approximate average airflow loss of 50% on a 2" thick core.
(exact loss varies depending on the fan, how it's mounted, the static pressure, and the PQ curve of the fan - some fans seem to push pretty well as the load increases, some drop pretty fast, on average thicker fans handle flow resistance better than thin ones)
I then made the assumption that doubling the thickness doubles the flow loss, giving an effective flow of 25%.
There may well be problems with my methodology, but I do feel comfortable with my bottom line assertion that doubling the rad thickness is not a good way to go for better cooling.
