Yep, changing the output representation was indeed the bigger improvement. There's a better way of handling the base case too, which I've only just found, but to beat your solution I have to use two of your ideas so: {mf_W=)1|{mp},\fe=(0a*+{)J}%}:J

mf e= is much better than what I'd found when I knocked up a sanity test while the question was in the sandbox, but one improvement I found which you haven't used is to do the mapping for the twos as (0a*+ - i.e. ri{}sa2*{mf_W=){mp},\fe=(0a*+0j\{)j}%*}j. And there's a much bigger improvement as well which I'll give you a few hours' headstart on...
