Parametric sweep with geometry changes

I am simulating a semiconductor component that is liquid cooled from two sides. The model is built like:
- upper cooler
- upper heat spreader
- heat source
- lower heat spreader
- lower cooler
Turbulent flow and heat transfer are only coupled in one direction. First, the flow in the coolers is calculated and then the results are being used in heat transfer as values of variables not solved for.
So far, no problems.
Next I want to do a parametric sweep in the heat transfer step, in which the thickness of the heat spreaders is varied.
This leads to my problem:
Subsequently to the change of heat spreader thickness, the position of the upper cooler is changed a little upwards. But this change does not apply to the results of the previous step (of course) so that the values of variables not solved for (namely the flow field) do not coincide with the now upwards shifted position of the fluid volume.
Does anyone have an idea how to handle this without doing flow simulations for all possible cooler positions?
