Even if you don't go by how Nanja describes Kidou, there is already solid proof in the manga that reishi composes Kidou. One good example of this is that Nanao created a barrier out of Kidou to hold off Haschwalth. Haschwalth, in response, slowly was pulling away reishi from said barrier in order to weaken its constitution. Therefore, said spell was made out of reishi. The fact of the matter is, more evidence supports that Kidou is composed of reishi more so than the evidence that Kidou is composed of reiryoku, which, there really isn't any besides personal speculation and what Bleach Wiki wrote on their Kidou page; which doesn't supersede actual manga evidence. But that's just my take on it.
