i'd venture to say no...
if the pila a's were used, there would need to be an adapter in order to allow 2-123's to fit without rattling, and as it turns out, the cells are also too big to work with the current tailcap solution.
if you wanted to use the thicker sells, a whole new body and tailcap would need to be made /ubbthreads/images/graemlins/frown.gif
