How about 1:50?

Flying on award reservations on separate networks, so different reservations/no interline agreement.
DTW-ICN (DL) lands 6:25p, and ICN-SPN (OZ) leaves 8:15p. OZ lists int'l check-in closing time at ICN 50min before dept. Odds of clearing bag claim/customs and getting to front of Asiana ticket counter in 60 min? (The ICN Transfer Desk does not handle claiming/re-checking bags, correct?)
