I am not clear on your particular use case(s).  Plasma desktop is usually 
installed by setting the appropriate make.profile:

$ eselect profile list

If you are looking for some minimalist desktop, a Plasma DE plus KDE 
applications with hundred of dependencies is probably not what you want.  
Also, I think Plasma DE and most DMs will pull in X11, because:  a) they work 
both with X11 and wayland;  b) many X11 applications can only run in X using 
XWayland.  XWayland is an X Server running as a Wayland client to enable 
displaying native X11 client applications within a Wayland compositor 
environment.  I haven't looked into it at any depth to see if you can strip a 
heavy DE like Plasma from all xserver dependencies - I'd guess you can't.

OK, select the Plasma profile, then have a quick look at:

https://wiki.gentoo.org/wiki/KDE

You'll need to disable some USE flags of plasma-meta to avoid dragging in 
things you may not need/require, like 'display-manager', 'sddm', 
'accessibility', etc.  Eventually, after you update @world, add any kde-apps 
*-meta packages you need.

However, if you intend to use wayland for the most minimalist of purposes, 
then you may want to consider something like Wayfire, instead of Plasma.
