Short answer . . . no.
Long answer requires more info from you.
Are you wanting to use the Schmidt SKM-88 mechanism, or the Schmidt SKM-192, or ?
I have done something similar to what I think you are wanting to do.
I used the SKM-88 click mechanism. . This required changing the length of one of the brass tubes and making a threaded mount for the SKM-88.
For some pens, I also made a short extension piece for the "plunger" of the click mechanism.
Mounting the SKM-88 click mech required a tap to match the threads on the SKM-88 (M7 x 0.75, into D-size drilled hole).
BTW, I assume that you know that PSI sells, in addition to their original Slimline Pro kit, a much newer kit called the Slimline Pro EDC which uses the SKM-192.
The SKM-192 mech is quite different from the SKM-88 and is not mounted in the same way. . I prefer to use the SKM-88.
