I love this cycle -- it's cool to be able to give an "allied color" card to both of a color's allies at once! Crackling Shell is my favorite. Limestone Wall could probably cost less, but it might look worse on paper than it plays.
Of course, your next mission is clear: do the same thing for allied color combinations and their common enemy.

Meek Pupil -- the flip side is interesting (if a little unusual for blue), but it doesn't feel particularly legendary to me. Kinda iffy on this one.
Increased Might -- very cool. The only thing that jars me a little about this is how bad it is as an Aura. I feel like you'd only play this card on a creature with power 5 or more, in which case you might as well just make it a non-flipping legendary enchantment! Making it +3/+3 and 8 to flip would help.
Mana Siren -- Neat-o
Minor Devil -- Love it! I especially like that both forms have an ability with a similar trigger.
Reading these just made me think -- it would be interesting to have flip cards that started out Legendary, but could be demoted to ordinary under certain conditions.
One way to make common Legends more viable in Limited is to give them leaves play abilities...
Varness, Bonebark Dryad :1mana::symbg:
Legendary Creature - Skeleton Dryad

When Varness goes to the graveyard from play, target creature gets +1/-1 until end of turn.
