The moon Lignumis (https://mods.factorio.com/mod/lignumis) is something I've recently tried with On Wayward Seas and I found a conflict, the water cane is preventing their wooden flooring from being placed because the pressure is too low... But, I had an idea and I have posted a thread on their mod page as well.
Since the wood flooring is probably meant as both a wood sink and an early footpath, what if:
When Lignumis is installed, the wooden flooring is made more expensive and "floating", so it'll work like the refined concrete in your mods, but wooden platform can't be placed on land.
That makes an island map much more feasible for Lignumis, and for balance maybe make it so the wooden platform can only have wooden industry built on it and landfill (later refined concrete) is for the heavier stuff.
Also, maybe perhaps if cackling.fiend agrees, the cuttlepop and sunnycomb from Wayward Seas could be changed to a range of pressures between 1000 and 2000, and the pressure on Lignumis could be adjusted a bit to match that range so we can simulate spreading alien fungal species to new surfaces for industrial profit.
There's also volatile resin that could be useful in later game in flamers on Lignumis.
Again, a though for a bit of mod cross-over "fun"
