Since the events of 5 Ronin take place entirely in Japan, there's absolutely no reason this should have any bearing on the characters of 1602. Well, unless O-Chio Braddock decides to go looking for her father's family...
WMG / Marvel 1602
The 5 Ronin miniseries is set in the 1602 universe5 Ronin is set in 1600, so the timeline matches up — especially with the fact that Deadpool, Wolverine and the Punisher are all (in-universe) older than Spider-Man or the original X-Men. The only problem with this idea is that both series have a Hulk; except, really, the 5 Ronin Hulk is only the Hulk in that you wouldn't like him when he's angry. He could just as easily be the 1602 equivalent of Thunderbolt Ross.
