In therory it's possible but essentially a bodge!

You would need to move the chassis mount 3" further away from the wishbone mount, so will need some chassis re-design, then fit a 1" spacer metal spacer under the bumpstop to limit travel to the 4" (3"+1" bumpstop) of the original design.
Getting the spacer on the damper rod will depend if you can 'undo' the damper top mount.

It's a lot of faffing around so the 16/11 dampers would have to be good AND cheap.......
