What's the lowest reported Surveillance so far for the rare drops in the 4* sectors? You'll only be able to hit 160 Favor if you lower your Surv to 185. And with 175 Surv, you can boost your Favor to 165-175. But that might just make the Surv too low to get the rare items in there.

But if the lowest possible Surveillance for the Meerkat is indeed 190, then yea it would be impossible to get enough Favor at the same time for the double dip.
