From what I recall as long as you set USE="wayland" globally and re-emerge 
world with '--changed-use' you should able to launch your dekstop in wayland, 
rather than Xserver.

https://wiki.gentoo.org/wiki/Wayland

There is a caveat, to make things simple: your desktop environment should have 
full support for wayland compositing - e.g. Plasma and Gnome come ready baked 
with their own compositor and will run in Wayland.  Window managers which do 
not possess a compositor will require one installed separately, as noted in 
jdm's post, but then we're getting into a box with a pile of bits in it.

To launch wayland you can either install a Display Manager and select to start 
wayland from its GUI options, instead of X11, or you can run the stanzas I 
provided above.
