Unknown what effect if any.

Most of Ainz's summons have been with skills or Super Tier spells, which don't seem valid to use with metamagic. And [Extend Magic] probably raises the effective tier and hence the mana cost of casting a spell, which means it may be a poor choice compared to simply recasting the summon when it's duration runs out (or gets killed before that).
