I can't say that i have actually tackled this, but I have some experience with the functions you mentioned. Heatmap takes an hclustfun function parameter. You can create a custom clustering function. I don't believe there is a rule that says you have to do actual work in that function call. Look at just returning the results of your more complicated clustering in that call without actually doing the calculations.
