The smallest fully rigged gun I was able to achieve is a 9 pounder at 1:100 scale.
This had to be done by rigging the barrels and breeching lines first, then slipping the gun tackle rigged carriages under the barrels and gluing the eyebolts of those gun tackles to the bulwark as the final step. The use of hooks had to be abandoned, and eyelets were tied to blocks using black sewing thread.
Everything was accomplished using an eye magnification headset and careful tweezer work using CA glue and pre-drilled holes in the bulwarks. Even so, it is delicate, and it is difficult not to tear a a gun tackle apart or crunch something.
The four 6 pound sakers shown at the forecastle bulkhead proved too small to allow making of gun tackles at 1:100 scale, and the carriages had to be scratch built. It may be possible to create simulated blocks using globs of glue approximately 0.5mm in diameter onto thread in micro gun tackle assemblies, but since these sakers were covered by the upper forecastle deck anyway, that attempt was abandoned. Personnally, rigging cannon carriages is one of the more interesting and fun parts of a build.
An idea occurred to me. If the gun tackles were to be displayed in storage configuration as shown in
@jbradford's photo below, perhaps the blocks could be simulated using tiny glass beads, the ones usually used in making simulated parrel trucks, and some thin thread? HiS Model in Czech Republic sells very tiny etched brass eyelets which could be used in the tiny gun tackles.
