Using my example:

mkdir a
echo "a/x" > a/x
echo "a/y" > a/y
echo "a/z" > a/z

mkdir b
echo "b/y" > b/y

mkdir c
echo "c/z" > c/z

mkdir d
mount --bind a d
mount --bind --overlay b d
mount --bind --overlay c d

cat d/x
"a/x"

cat d/y
"b/y"

cat d/z
"c/z"

Then...

echo "d/w" > d/w would create a new file in directory a.
echo "d/y" > d/y would replace the file b/y
etc...

Is this sort of thing possible, or are there fundamental reasons that 
would make it difficult?
