I think most folks lump herbivorous Tangs (petros, trophs, gobies - to some extent) together and carnivorous Tangs (including fronts) together because of differences in not just diet, but also behavior.
I would think trophs may be a bit too aggressive/spastic for fronts.
So long as you start with Altolamps big enough, it should not be an issue. Both are very slow growers.
