I'd ditch aether and the RoLs as well. Sanctuary would be much better than Luciferin; it would heal way more in the long run, still work with Miracle, and protect you against discord and all that fun stuff. Diamond Shield would be an excellent choice too; absorbing 3 damage from everything would be very nice here. If you haven't got that, Titanium or Tower Shield absorbs 2, and Solar Shield/Buckler will help fuel miracles. Shards of Gratitude would be a good addition if you have them.
If you want to win by damage, Animate Weapon/Morning Glory might be a good choice. There are only a very few cards that can stop that. If you want to win by decking your opponent out, keep in mind that some decks are going to be too big for this to deck out.
If your heart is set on keeping the aether in there, I think you should use another creature to fractal. RoL is a good early choice; you get lots of quanta and your Hope gets very strong, but RoLs aren't going to kill anybody with a shield up. Pick maybe 2 or 3 copies of your favourite big creature and put them in to fractal in the endgame. Golden/Light Dragon, Shrieker/Elite Shrieker, or Archangel would probably be the best choices. Don't pick an aether one; you won't have enough quanta to do that.
