Agree with Adam, too. Half the staves I work with look like that!
The splice looks so smooth, I almost can't see it on the back pic, looking down. Unles the splice iteslf is off, i say go with what you have.
Do this. Work down the limbs a bit on the sides to expose rings and get a nice flat surface. Follow the twist, don't try to align limbs to the handle by carving off wood. Use faceted wood removal techniques to thin the limb down to maybe 5/8" thick or so. NOW, with enough clamps you can heat treat the whole thing to remove twist, or set yourself up a good one-limb-at-a-time steaming system and get your angle and twist corrections.
That lateral curve is the monster that taught me to ALWAYS restrain staves from saplings and branches.
