I have no experience with the Aikido you mention above (Tomiki and Mochizuki), but I agree, and yes, thank the heavens for Judo's influence!
You would love it if you tried. You fund yourself "fighting" for shihonage-ing and following up with a ude hisigi juji gatame in a blink. That's what I meant
Of course, if you have the time to take aikido, judo and BJJ that's great!! What I meant with the figuring it out thing, is that once you are experienced in those systems, going from kotegaeshi to kata or kesa gatame just come without thinking how to get there. Something you won't learn in judo or aikido alone.
