If WWE creatives were at least a little creative, they would use the fact that Alberto Del Rio, Ricardo Rodriguez and Memo Montenegro are related.
I can easily imagine one story about family's legacy, honor, brotherhood, treason, greed, dishonor, fear of failure, masks and their symbolics in lucha and finally redemption.
Turn the light on and imagine (of course the dialogue would have more spanish words on TV)
Del Rio is beating Ricardo in the ring for one cheating failure during one match. The poor guy is crying and betting his master to stop surprisingly calling him hermano (brother).
We suddendly hear Del Rio's music but with somebody else's pictures on the screen. One unknown man goes down the ramp and up into the ring. He took a microphone and speaks to Alberto ...
My brother, I thought you would change. I thought you would finally become one honorable man and stop deceiving our family. Stop this senseless beating and this senseless joke of your life.
Del Rio stops to beat Ricardo and looks at him surprised, almost afraid and in shock while Ricardo hides behind the new comer. The new comer looks at Ricardo and asks him to stop worrying.
Don't worry Ricardo your second brother is here.
He turns to Alberto
Alberto you are a shame for the family. You were supposed to protect and to help our younger brother and I see that you turned him into your own chihuaha ...
Del Rio tries to answer in spanish, he speaks quickly we can't understand anything. The new comer suddendly takes a lucha mask out of his pocket and holds it to him before to speak.
Older brother do you remember this mask ? Do you remember your own family ? Do you remember your honor ? You were La Escencia De La Excelencia. As good as our uncle, El Grande Mil Máscaras, and now you are just one angry dog hungry about wealth.
You were a member of our familly, you were a Rodriguez and you chose to change your name. You gave up your mask and you gave up your name. You are a shame for your blood and for all luchardores del Mexico.
I was sent here by our uncle, you lost your name and you lost your money. You are now disinherited and deprived from the family wealth.
Del Rio is confused and seems to begin to cry. He can't articulate a word and falls on his knees. The new comer throws down the mask in front of him and goes out of the ring with Ricardo, but stops at the entrance of the ramp and turns again to one crying Alberto left alone in the ring
Remember who you were my brother. You were a technicos, a good guy, one honest man.
The unknown wrestler and Ricardo leave the arena and begin one tag team career while Del Rio disappears in obscurity.
Five weeks later : we see Alberto Del Rio coming into the ring after one long absence. He holds a mask in his hand and begins to speak about his familly, his dreams about wrestling and about honor. He tells us that he wishes to avenge his honor and goes with his two brothers in one fratricidal feud.
This feud will last approximately twenty weeks full of great matches and finishes in one happy end when Del Rio's decides to save his brothers from another wrestler and to wear his mask again. The Rodriguez are now well established on WWE.
Alberto Rodriguez : tweener individual masked wrestler
Guillermo and Ricardo : tag team (unmasked or not)
We can even use a story prologue with one mysterious masked Chimaera randomly attacking luchadores (Sin Cara, Rey Mysterio, Hunico, Epico and even Del Rio) showing that RR sought recognition from Del Rio and introducing this character.
It's possible to use Hunico and Epico and to create one new tag team if they act as hitmen for Del Rio. At the end of the story (redemption), one short feud between them and the Rodriguez family would be awesome to finish the story.
But I am not a WWE creative ...
