Well to do what you explained you simply use bitwise operations.
So say your depth value is N*3 bits and we'll call it d.
Then just store it as follows:
mask = (pow(2, N)-1)
r = d & mask
g = (d << N) & mask
b = (d << (N*2)) & mask
To get d back do:
d = r & mask
d = d >> N
d = d+(g & mask)
d = d >> N
d = d+(b & mask)
