That would be very interesting and entertaining, if it were the case - but the reality is, even a low-level caster with only the regular spell focus in divination can tell a clone from the real thing. Which means anyone with an amulet of Savras can tell the real from the fake! The reason for this is, the clone counts as an NPC... Which means they don't have an attunement (air, water, fire, etc), which is immediately discernible compared to every other player character.Additionally, epic diviners can recognize projected illusions when examining, if their caster level is above that of the illusionist.
I guess I'm saying this partly in hopes that the ESF:I clone gets some goodies beyond a fix to what appears (?) to be an oversight on the developers' part. It's really hard to find the right circumstances where the thing would be useful in the first place, and it comes out to mostly just be an amusing little gimmick, or an accidental misfire when you're really trying to send a message to someone and your finger slipped and hit enter before you typed a name. When you want to bluff that the clone is the real deal, the fact that it can't even speak different languages or can't cast spells or turn on its heel without moonwalking already makes it a hard sell. Fun when it works, but extremely difficult - and thus, rarely utilized. Thanks for coming to my TED Talk.
