No, I think you are fine as you are doing it
is mushroom compost available to you Marvin? It is superb for clay soils. A bulk delivery if you can. I would also use that clay soil.....mix compost, grit anything with it breaking it up as thoroughly as you can. Keep it dry; cover it from the rain.
If you cannot get mushroom compost can you get a load of manure and grit to mix in?
Hard work but you are winning..a quarter way through so half way through the first half!!! ha ha
