it seems to me that some shrinking is possible, but there are limits
that don't apply to ics.

perhaps the swept area (air :-) can increase faster than the blade area
(the weight of the steel blades, etc.) if the blades are basically in
tension, with no slenderness ratio limit, they can become longer without
becoming much heavier.
