Yes, provided that WW, who cooined it, agrees with you that it means wistfully. Word are for communication, and unless there are two or more people who agree on the definition of a bunch of letters that bunch of letters is not a word.

The fact that others don't like it or recognize it as a word is meaningless. Even tsuwm and Anu see collections of letters every day that they do not recognize as words until some other person gives them a frame of reference to know what the words mean. From now on when you tell WW that she is reacting ee'-ox-lib-bins-DAY-en-vlab then she and perhaps others will know what you mean.

Edit: You have the secondary stress on the wrong syllable.
