Just providing clarification here, yes, it would work but there's two immense drawbacks here. The first of which is the likelihood of losing your characters identity, a kido spell is made up of innumerable fragmented wills. If you allow these into you to the extent that you become a spell, you've essentially allowed yourself to be possessed. Each of these wills would seek to exert their control at once and the result might be that your character loses part of themselves to it. a small piece at a time. Eventually they might forget their name, friends and eventually, they'd lose their bond to their Zanpakuto if it was done improperly.

The other drawback is the whole "turn yourself into Kidou". It sounds like a great and powerful concept, but it's exceedingly dangerous. If you turn yourself into Kidou, well, you become Kidou. This means that your character assumes the nature of something that is transient and fleeting, and accepts it's influence on their body. This might lead to your character dissipating along with their spell, inadverdently killing themselves. Furthermore, unlike techniques born from Zanpakuto or users themselves, Kidou is entirely neutral, it will obey the whim of whomever exerts the greatest control over it. This would, if your character became Kidou or even became sufficiently suffused with it, allow those with a greater grasp on Kidou than themselves to tear them apart or achieve dominance over them.

Not to mention that they might again, inadverdently kill themselves if they make a misstep. It's like swallowing a sword in that regard.
