OK, I guess it's time to set a specific thread for this ongoing filter.
It is derived foundamentally from Lyle's tutorial on this subject.
Then I added some "heretical" lateral thinking (and Lyle, from his side, has changed his procedure), thus now there is a divergence (if Lyle wants me to drop his name from the filter's name because it doesn't implement his current thoughts, I will do it, but I'm still convinced his initial procedure is the ground, so IMO the name is appropriate).
If someone is so kind to perform testing, I'm grateful.
Here the current release, which supersedes the two previous posts (in any case the name is a bit changed so there is no "replacement" forced).
Warning: this version makes use of my ancillary filter modLCS, already published when I posted the CrystallizeN filter. If you didn't download already pls do it before running this one.
Enjoy (hopefully...)
edit: replaced with correct version, sorry Kimba
edit2: a test made with a big image revealed an error (because the G'MIC 3d elevation filter used inside accepts only a maximum width/height = 2048)
I posted an amended version on page 2
It has now been tested by Issabella, so i drop the one here and replace with the latter one.
here it is, please re-download if not yet done

note: Pat told me that the version put here last night isn't correct (I don't know why)
thus, removed and substituted again
here it is
---------- removed ------------------------------
new editTheWarrior discovered that the square sizes did not change: my typo error.
Thus I removed and reinserted with the amended version, tested by TheWarrior
