Shrub,

First, welcome to the site.

Yes, you can "move" the hot air from rooms in summer to the attic to be vented, but where does the replacement air come from? The outside of course.

If the outside air is cooler, then why not just open a few windows on the third and first floors and let natural convection do the work?

The other alternative is to install an efficient AC unit that would use the existing ducting.

I have been in London in the summer and I found it damn hot! Actually quite humid, but there were days in the mid 30's (mid 90s F to us non metric folks). And absolutely NO wind.

I found it otter than many days here in central Oklahoma (just north of Texas).

Keep thinking on how to use these ducts!

Steve
