Supporting attic bedroom floors without access from below

Two finished attic bedrooms have spongy floors (24" joists). Would like to firm up floors and facelift for use by teenagers without feeling like they're coming through the ceiling below. Without access from finished bedrooms below, would heavy (3/4") plywood (out to the attic knee walls) glued and screwed into existing joists help stiffen the floor or make it worse due to additional weight? Any other suggestions?

If you're going to "facelift" the attic anyway. Just pull up the subfloor & sister the joists from above & then put the new 3/4" sub floor down. Just adding thicker plywood won't help much. You need to firm up the joists.
