Based on the fact the Yachiru is back to normal, it certainly makes the case that Kensei and Rose could still be alive due to Gremmy being distracted, although it seems to me to be somewhat ambiguous at this point whether he used his imagination to "kill" them or if he used some other Quincy technique to do the job while Isane was distracted by the fake(?) Sternritter. Also it's important to note that this isn't the first time in this arc that a character (Byukuya) has been stated to be dead in one chapter only to be proven wrong later. I guess we'll just have to wait and see.
