I've played through the Oracle duo once, and they are damn good games; they're just held back by the godawful Subrosian and Goron dancing minigames, the awkward Mermaid Suit controls, and OoA's Head Thwomp boss being a complete nightmare to beat due to his unique mechanics.
They just need a bit of polishing to be truly excellent.
There's already a mod to make the Mermaid Suit control better, so that could be easily incorporated into an Oracle DX package; the Head Thwomp should be slowed down to make timing bomb throws much easier; and the dancing minigames just need better controls and more lenient timing, I feel.
