I have no experience with full-sphere systems, so please ignore everything I say. You don't say what order of Ambisonics you will be using. With first-order all speakers cooperate to localise a sound, so that when speakers above push those below pull. It therefore helps to have speakers placed above and below the height of the listeners' ears. Your proposed arrangement does not appear to do this, while the Observatory Vilnius arrangement does. With higher orders this is less of a concern. If the material you will be using is mostly horizontal-only then many speakers level with the listeners' ears helps. If the material makes full use of the whole sphere then the closer you can get to a Platonic solid the better.
