I do agree with @jhay, conditionally. It's possible to do that sort of thing, so long as the feel is different. Perhaps the first OS could be, say, Situation/Future/Preconception/Control, while the second could be Manipulation/Becoming/Responsibility/Control. Alternatively, it may be as simple as giving the IC different OS traits than the MC did--for example, the MC might have been Control/Temptation, while the IC might be Control/Reconsider instead. You might even be able to get away with just switching the Growth: a character Stopping Control feels different from Starting Dyscontrol.
(This is an interesting topic I've been thinking about lately, though I'd been focusing on IC handoffs. The new IC should threaten the same square, but do so with a different attitude or tone.)
