Steve's already said this but I want to say it again: no!

The Flow Label is totally orthogonal to diffserv, which has no need
of it, since it has its own mutable 6-bit field (more than enough).

The Flow Label is totally orthogonal to the MPLS Shim, which is at a lower
layer and is edge-to-edge, not end-to-end. 

As has been observed, the Flow Label is accommodated neatly by the IntServ
model.
