So, what do you suspect to be the growth rate? I think its not recursion around BB(n) so, is it w1ck*2? Or even w2ck? I believe it must be slower than BB2(n), because I think that TM can simulate game of life (although it'd take thousands of states,probably). And oracle can determine whether it halts.
