On a side note, would SIPs be a viable option just for the roof and (3) dormers?
In the garage or the future house? Garage, probably not unless the upper level will be heated. The future house, yes, ICF's & SIPS are often married.
Finally, would it make sense to install radiant heat flooring beneath the second story (to provide ambient heat below) since my eventual new house will have radiant heat?
I am assuming you are talking about the garage? If so, and you want a heated garage, Sure. Just beware that your garage will more that likely have a much higher Air Infiltration rate, so you may have to adjust your Heat Calcs to show that.
