Hartikainen said on a local podcast (1h21 and onwards, unfortunately only in Finnish) that he thinks an NHL return wouldn't make sense for him. He doubts his ability to adapt to current NHL speed in his age, plus he likes his current role and contract situation/salary in the KHL.
Another KHL guy to consider is Konstantin Okulov (RW/C). Leading scorer for CSKA, slightly younger than the aforementioned Zhafyarov. Prior to the start of the season, @Caser wrote in his article that he believed Okulov to be a "level above" to Zhafyarov, would be interesting to hear if his opinion has changed during the course of the season.
"Level above" might be not exactly the right way to interpret it, but I always liked Okulov more, yes.
