Nope, done that before when I cut a chain too short. Had to splice in another handful of links, recut it, then put in a second link. Better than trashing a nearly $200 chain. Come to think of it, I think that's the chain that's on my bike right now. It has about 11,000 miles on it which is what I get from any chain.
I wouldn't put the two master links adjacent to each other is all. No good reason, I just wouldn't do it.
--Wag--
