Can you adjust Khitan Ceiling height or lower the position?

I know. I know. I have picky eyes. It is very small things, but I cannot ~~. haha
Please see the images.

Compare to others. (oddly satisfying…)

To do this the whole mesh would need to be altered to that is was thinner, there isn’t alot of room underneath the ceiling as it is, and dropping it that slight amount may stop opjects like cupboards/furnaces/ any tall structure being placed in the room beneath it.
