If we're going by my recommendation to treat Summon Alien exactly like Summon Monster, then any summon-improving feat that would improve Summon Monster will also improve Summon Alien. However, many of these feats have prerequisites that the Binder would find onerous to obtain, while others are impossible for a straight Binder. Rashemi Elemental Summoning, for example, requires 'spellcaster level 5th', and a binder is not a spellcaster. Augment Summoning requires Spell Focus (Conjuration) which is worthless to a binder. The binder's summons are also already automatically improved by the pseudonatural template.
Even if the feats apply, I wouldn't honestly recommend it. I would prefer to spend feats on Favored Vestige (Zceryll) and Rapid Recovery, to gain a +1 effective binder level with Zceryll, and thus gain access to each level of summoned monster at the same actual level as a wizard instead of a sorcerer, and to be able to summon a creature every 4 rounds instead of 5. An Anima Mage may be able to make better use of feats like Spell Focus (Conjuration)...but I would also argue that the Anima Mage's feats are better spent toward metamagic feats or something else, as well.
