sekkajin would have too much kick back for the 8th hit to connect on the second time. This combo is possible in CT so try if you want. The second sekkajin would work on tager but you can't combo out of it.
I got a combo. I don't if this was posted yet but
throw>cancel first hit>snow flower storm(8th hit)>66>5c>jb>jc>jc>jd>whatever you want. You could end it with ice car but since this is an ice reset combo you can do other things as well
