The answer is "No". One may define the CMBR isotropy frame as an
absolute frame of rest, but it has no special property apart from
that; there is no physical consequence of having a velocity with
respect to that frame which leads to anisotropy in any physical
system having such a velocity. The CMBR anisotropy itself is the
only observable "consequence".
