Anyone do a bastard pack or add a main leaf?

Looking to firm up the ride and add just a touch of lift to my 71 suburban. I have access to some square body suburban springs and was considering removing its main leaves to add a leaf to my springs.

I'd cut the ends off and make them the same length as my main leaves, and add them to the stack just below the main leaf.

I've done this on my Jeep Cherokee and really like how it turned out - added about an inch of suspension lift and firmed the ride just a bit. However I used another set of the exact same springs as donors.

Thoughts?
