A couple of things,
@Jenna :
1) What many fluffy bunny aikidoka (not saying that you fall into this camp, just dredging up an ancient, derogatory term)-what many aikidoka forget is that Ueshiba was extraordinarily strong in his youth to middle age, had studied a variety of martial arts, had hunted boar with a sharpened stick (!!), had been some sort of militray butcher in Manchuria, and had interactions with a variety of martial artists as well...his students came from a diverse background of martial arts.
So let's assume, for a minute, that when he said that "atemi accounts for 99% of aikido," he meant that
atemi accounts for 99% of aikido.
Then take a look at the atemi that exists within aikido-it is not only not exactly representative of atemi waza-it is, in fact, it's modeled on sword striking...what we have in aikido atemi waza is a
symbolic strike and movement, meant to represent a person attacking, in order to enhance movement, timing, and blending. The assumption-in the beginning-was that the student, having studied other martial arts, would understand this, and have been exposed to real strikes in his other training.
(You'll see that "
other trianing" is a continuing theme here.)
2) Aikido, as a way to "aiki development," is really meant for polishing an already competent martial artist with (ahem) other training.
If you ever are interested in any recommendations for additional training, PM me.....I'd recommend, though, at a a minimum, a striking oriented art like wing chun-I'm not talking about MMA competition, here, hypothetical or otherwise, I'm talking about making your aikido more useful-Seagal sensei (since he was mentioned earlier) regularly uses techniques-blocks and strikes-from his gung fu training as entries for aikido. He also does a few things that are size and background specific, just as you should:I've always assumed that you're somewhat petite.....
Some kind of groundplay, like judo, would also be a good fit......
