First of all, thanks a lot for your interest in WPE! Remember that depending
on the time of the day, many of us may be available in the Freenode #webkit
channel as well -- in case you want to shoot some quick question our way :)
I will comment inline below.

While this could work, I haven't used the “meta-wpe” layer myself for quite
some time, I would strongly recommend you to use the “meta-webkit” layer
instead. The reason for this is that we try to maintain as close as possible
to upstream WebKit, and because of that already supports WPE WebKit version
2.20.0, which is our first *stable* release. You can find the layer at:
The wiki for this repository has some notes on how to use it in general, and
some notes in particular for i.MX6, which happens to be one of the platforms
we are been actively developing for:
I am confident that the instructions in this last link should get you a
working image. Please give it a try, and let us know if you run into any
issue -- we want to ensure that the build process is as smooth as possible
(always hard when cross-compiling) and feedback is always valuable.
As for a simpler way, I am currently in the middle of preparing an overlay
for Buildroot (using BR2_EXTERNAL) for WPE; but it still needs some love
before we can recommend it.
Last but not least, you can always build for x86_64 and run your WPE on your
laptop/desktop PC. It's probably the easiest option, and even if your final
target is some embedded device, you can use this for faster development.

Westeros is not a requirement. It just happens to be the compositor that the
RDK  images tend to use by default. WPE will happily work on most Wayland
compositors  using the FDO backend or the RDK one (with the Wayland support
enabled), and directly on the framebuffer if you use the RDK backend (with the
i.MX6 support enabled).
I hope this helps.
 At least we know Weston, GNOME Shell, and Sway/wlroots work fine. I expect
other wlroots-based compositors to work as well.
