For me, not if IK is definitely straight. I don't think sex is that big a deal to him and I don't really think he's defined by it no matter what his inclinations. And under those circumstances, I don't think Solo would make a move to seduce him [again, no one in my memory has tackled that scenario].
Although ... why not? If Solo was interested, and felt Illya didn't worry much about sex one way or the other, why wouldn't Napoloeon make a move? (granted all the standard reasons that they might not say anything, the threat of outing, risking partnership, all that) It seems to me IK's ambivalence, or philosophical attitude if you like, would permit at least the polite opening of the topic. Napoleon's ego might not want to be bothered trying to attain someone who's indifferent, of course -- or he might consider changing that indifference to interest to be a challenge...
