I have had another go at substituting dumbells again tonight with a set of deadlifts using 1 dumbell, a set of basic swings by holding one dumbell by the plate.
A set of bent over rows using 2 dumbells, a set of squats using 2 dumbells, all done with 12kg dumbells followed by a walk to the park with my daughter.
There is some movements that cannot be duplicated by dumbells due to the shape of the kettlebells, still it gives me an idea of what to expect and while i didnt push myself any exercise is 100% better than none.
