qo- vord formation

[-JKP-]

...
Here are some examples:

qotchoiin
qotcham
qopchor
qokShol
qotchol
qoteeol
qokcheo
qokShy
qokchy
qotchy
qoteeey
qokeey
qokey
qoky
qoty
qokeeo
qotcho
qodaiin
qosaiin
qotaiin
qokaiin
...

If we take your examples and combine them with some of the concepts I mentioned in my first post, here is another way to look at it (imagine that o and y are also functionally equivalent):

qoky
qoty
qokey
qokeeo
qokeey
qotcho
qokchy
qotchy
qokShy
qokcheo
qoteeey     [I am confident that this vord belongs in this group and not the following group]

qoteeol      [It's hard to format on a forum post, but I would put this to the side of the above group rather than below it, so they look like brothers rather than cousins.
qotchol         What distinguishes them from the previous group is the pairs (something I blogged about a few years ago).]
qokShol
qopchor
qotcham

qosaiin      <-- Note how the s shape is contained within the d (that's why I shifted list order from less complex to more). I'm not sure if this has been mentioned previously.
qodaiin      <--  
qokaiin      <-- It is more obvious, of course, that the k shape is contained with the t.
qotaiin        <--
qotchoiin
