I have seen some stands that the screw is removable. If you could find these you could keep extra pins or screws and just leave the one on the stackers on the stackers and put the others in for regular cymbals, or get a threaded long nut to screw down and screw another threaded pin 1/2 in the long bolt and screw your stacker on that! Will probally have to go to a screw company to find a long nut. They are usually hard brass. Make sense? I personally do not use stackers. I just get more stands. I currently usually use 10 Cymbals counting 2 Hi Hats. One is a Pearl remote Hi Hat mounted 1/2 way up on a telescoping boom stand with a 14" crash above the hi hats on the boom. The remote hat goes between my 1st and 2nd tom. Look at the photo below and the Remote Hi Hat is between my 1st and 2nd tom. I had a 20" crash in this photo mounted on the boom with the remote hi hat! !
