I'm afriad not, for two reasons. The first is that scaling them down (any level of significance) would essentially require a rebuild due to ensuring all parts can make the minimum wall thickness, which requires a fair bit of time (which basically means it would require a commission if I was gong to do it). (While I was able to straight scale them for the gentleman who wanted them at 1/87th, that was a small enough change to still be (just) in the margins of error).
Secondly, the absolute smallest scale it would be possible to do them would be 144th (12mm), due to the wall thicknesses. Smaller than that and you are really getting out of acceptable scale distortion for printability.
