No, I've never seen such a thing. Basically, you just hightail it from the airport door to your plane as quickly as possible. You get a bit chilly in the process.
Although I get that you were talking about a purely hypothetical situation, if I had to bet I'd say this scenario is most likely to happen at SLC. (Hub airport, RJ-to-RJ, warm-cold-warm, with the boarding happening outside.) Maybe DEN too, although bigger RJ's get jetways there.
I have had this outdoor exposure at JFK and ORD too. At MSP and DTW almost never anymore. None of them provide outdoor wear as much as they provide outdoor exposure.
