totally respect your perspective here. I will amend what I said and just state that "it's silly for ME to be running manjaro when rolling is not important to me." I guess I could run SolydK, but I like the Mepis community. Not here to make waves, I appreciate all of the work that those who have been dedicated to this community and distro have done. I really do like KDE.
I totally understand, back in the old Mepis days I was a total KDE fanatic! Still cannot stand Gnome but Xfce is a different Gtk story for me now.
Please please don't think I was wanting you to leave? I have 'heaps' of back pain at present and I appear like a grouch to everyone?! I was just making a couple of suggestions you may care to look at. I am sure you could achieve a satisfactory Plasma outcome from downloads here.
My real point (and concern) that I was trying to make was more about developer involvement in producing yet another version of the distro. It's not necessarily a simple task and these folks are superhuman I know but, I just don't like more and more pressure to produce user wants. Hope that makes sense. I used to do a bit of this work and I know it can quickly become a real burden. I currently support a couple of hundred Linux users who use different distros and desktops but I only support 'default' desktops for each distro.
Regarding the desktop, from memory, one of the main hassles with mixing them was the mess the menus ended up in! But hey, I haven't actually tinkered much with this sort of thing since I settled here, it may be a lot better than it used to be. I would suggest you create a new (temporary) user and fiddle around with your experiments in there until you are happy. If you don't like it, blow them away and have another go!
