The rambox32.rom file included with ClonixConfig burned in a Clonix-D module at page 8, returns 31.34 in X and "-RAMBOX 32" in ALPHA.
In the RAMBOX users manual, their example returns 30.35 in X and "-RAMBOX 1B" in ALPHA.

I also noticed that there is a "-RAMBOX 32" and a "-RAMBOX 1B" variant. However, I've never analyzed what the difference is. I've also seen 32K RAMBOXes with OS/B from the 41CY. They run fine, although the bank switching functions (PG<>, PG01 and PG10) obviously don't have any effect.

can I copy the ROM from the Clonix-D module to the second block of the RAMBOX, deactivate block 1 at page 8 and activate block 2 at page 9 ?

I think I have one with the "-RAMBOX 1B" operating system. I have to dig it out and save the ROM image.

I think your approach should work, however, I've never tried it as the 32K RAMBOXes I've got were all running fine.
