Have you calculated how much air conditioning would you need during the summer? That would determine if it's worth the extra engineering to make it heat and cool (not trivial on a hydronic system) or if it would be better to separate it. Also note that while 80F water would work for floor heating, it would feel pretty cold for showering. (Not sure what your preferences are - some actually enjoy cold showers!)

Also remember that it's quick and easy to modify stuff on the water side, not so much on the refrigerant side.
