A good friend of mine is a black belt in Aikido. He and I used to spar quite a bit. He was never a challenge till he got in to BJJ. Then he regularly kicked my ass.West, you are comparing apples and oranges. Karate is a system of lateral blocks, punches and chops, shodokan aikido is totally different and involves locks, traps, and a redirection of force.
Karate gives a girl an inherent disadvantage against a bigger guy, whereas aikido actually favors a smaller, lighter person.
