Well, ecological data are usually not included in cladistic data
matrices because the ecology of a species directly influences its
habitus and so including the ecological data to a morphological data
matrix would obviously lead to non-independent characters and would
give unjustified weight to characters which evolve dependently and very
likely quite homoplastic. And the coding of non-independent characters
should be avoided if possible.
But other than that, nobody hinders you to put ecological characters in
your data matrices (except maybe the reviewers and the editors).
If you are suggesting to make a cladogram exclusively with ecological
characters - that's not a good idea.
What you can do is use a cladogram derived from morphological and / or
molecular characters and map ecological characters on it to see how the
ecological needs of a group of species evolved. This is done, as far as
I know, in the interdisciplinary branch of biology called EVOLUTIONARY
