Are there any SAK modders, here?

I've done a few, but I suspect that what you want would require fabricating a new spring which is beyond my comfort zone.

 

It won't work. The spring for the main blade isn't thick enough for the scissors, and even if it was, you'd have to remove the main blade as well to make room.

 

Just out of curiousity, can one use the scissors and back-spring from an 84mm Climber?

The pin locations are different on the Cellidor models than the Alox models, so the spring will not readily transfer.

 

If its something you are interested in, you might want to email Vic and let them know. 84mm doesn't get as much love, but they did do the Pioneer X, so maybe they would do a Cadet X if enough people asked.
