Well... if you're using 75% glycerin and another 5% honey, you're going to have a very syrupy liquid. I would cut it with some distilled water or use PG or VG.
As for the honey, it shouldn't be to much of a problem but... I would definitely shy away from it just in case. You don't wanna be burning sugar and ruining your atty. I almost did this by trying to use pop syrups for flavoring.
