What do you mean?

split[A]    select='not(eq(mod(n+1\,5)\,3))'       [C]interleave
      [B]split[D]select='eq(mod(n+1\,5)\,2)'[F]blend[D]
              [E]select='eq(mod(n+1\,5)\,3)'[G]

I created the filtergraph by hand. I don't know what folks expect, but since duplicating pads (e.g., 
"[A] [A]") just takes up space, I didn't duplicate them. I don't know whether that relates to "reuse 
filter pad labels". Could you put some 'meat' on your 'bones'?
