Provided that your 3200 amp load is 125% of the continuous load plus 100% of the non-continuous load, I'd say OK.
Few things are harder to put up with than the annoyance of a good example.

With six disconnects, and as calculated, it is Code compliant. Good to go. \:\)
If it was easy, anyone could do it.
