Does anyone have a solution for adding insulation thicker than the
studs? It's behind a knee wall area in my attic. Google came up with a
few patents on devices but I haven't seen anything for sale. The only
thing I thought of was butting 2x4s against the old ones and nailing
them together. Any better ideas?

Pull the fiberglass and replace it with foam... You stop any air infiltration
and get a higher r-value to boot.
