Is it possible to produce the band structure of higher order guided modes

Yes.
antisymmetric mode can not be selected this way. However, (run-zodd)
does not work neither since this considers "TM-polarised" modes, unless
my interpretation of even and odd is wrong here. Is there another

Your interpretation of even and odd is wrong.
There are no purely TM or TE polarized modes in a photonic-crystal slab.
There are only even and odd modes, assuming the slab has a z=0 mirror
plane.
The even modes are often described as "TE-like" and the odd modes as
"TM-like", because in the z=0 plane itself an even mode is TE and an odd
mode is TM. Moreover, for a *thin* slab, the polarization doesn't change
much as you go to non-zero z so it is reasonable to think of the even/odd
modes as mostly TE/TM.
However, if you slab is thick enough to support higher-order modes, then
the higher-order modes are no longer accurately described as mostly
polarized in one direction or another. You can only call them even and
odd. And the the next-order mode of an even mode is odd.
