Question about 窠

First, look at this:

[www.cantonese.sheik.co.uk]

窩

[1] [n] nest; den; lair; hideout
[2] [n] abode; residence; home
[4] [n] sunken/hollow place; pit

Then look at this:
[en.wiktionary.org]

Definitions
窠

bird's nest in cave; nest
(literary) simple dwelling
(literary) empty space; pit; hole

Now my actual question: can this character 窠 also mean nest; den; lair; hideout, or sunken/hollow place; pit?

I need EXPRESSLY this character that you see above, 窠, because ON THE INTERNET PAGE it looks symmetrical -- non-symmetrical characters will not do, NO.

I need it in a story. Ancient characters sometimes look symmetrical, but for a certain reason I cannot use them in the story.

And the meaning "bird's nest" is completely useless to me. It is not what I need, I need the meaning hideout, den, lair.

If this does not work, then I must think of something totally different.
