Kettlebells are focused on compound exercises. I don’t know where you came up with this:

If dumbbells aren’t available, kettlebells are a poor substitute for dumbbells, whereas if kettlebells aren’t available and dumbbells are, dumbbells are an OK substitute for kettlebells.

I can’t think of any dumbbell exercises that couldn’t use a kettlebell if it’s all you had, but dumbbells are not well suited at all to kettlebell exercises.

And I don’t know why you hate swings, they’re a fantastic way to build squat form.
