Aside from shipping, here're some other headcanons!

This is how I think the keens in Dota relate to each other age-wise. I confess the second digit of their age was kinda randomly chosen, I thought more of the "decade" they are in and who is older and younger.

I guess this is also how I imagine they relate size-wise. Since Snap, Timber, Alch and the Techies are "smallkeen", I imagine they are smaller than the others.

I think the Techies come off as the younger ones because they are so reckless. Meanwhile, Timbersaw is one of the few (male) keens who does not sport a beard, so I naturally think of him as younger too. Lastly, Gyro and Snap act the most like typical grandparents, so I imagine they are the oldest.
