I'm not sure whether you're joking or not, but I'm going to react anyway. How exactly did you come up with this idea? Destiny and Skyrim were made by different companies, why would it be in the same universe?
Also, Phobos and Deimos are pretty small, possibly just asteroids caught in the orbit of Mars. Masser and Secunda look gigantic.
Then again, you might be joking/trolling and I just made a fool out of myself by reacting.
