Probably not because they would look too much like pajamas. I have worn sweat pants out in public, though. Since "joggers" are popular and often they are difficult to distinguish from sweat pants, I did not see it as a big deal.
The Scots version is called trews (but they're not really sweat). The kilt is a much better way of wearing plaid.
