Anyone can do anything just by practicing. You seem aware about the B22~RMS Cancel which means you're probably also aware it's + on block (+4 I believe, not sure though not a Flash player). Cancels take getting used to for sure, but if you hit up the lab and practice the cancels for a while you'll get them down.
Besides that, try looking at some Flash footage to analyze what Honeybee does in the neutral and what reads he makes when. Neutral is where Flash struggles the most as far as I know, so be sure to check out footage of good Flash players to see how they deal with it.
