Yeah you see it is all possible and I agree with all of that however it all adds complications. If only the modules are rotating but other parts are not then you have complicated bearings and access to add into your space station. If everything is rotating then you have problems pointing antennas, solar panels, other sensors at stuff (your solution of separating the power and the station merely complicates it further).

It could all be done. Of course it could. But at what cost and would the benefit of making your astronauts a little more comfortable justify that cost. Well maybe if the conditions being experienced were life threatening, yes. But these conditions do not appear to be serious and so would never justify that extra cost. Not just the cost either, the more complicated something is the more likely it is to fail.
