User blog:RenaissanceReaper/Should I change Rivals?

Hello, currently I have a few characters I created on here that I am thinking about switching their rivals. Here are the rivals and whom I would change them to

Original

Chell vs Corvo

Booker DeWitt (No Rival I switched Hawke to Commander Shepard)

Eleanor Lamb vs Chimera Hybrid

Changes

Chell vs Booker DeWitt

Eleanor Lamb vs Corvo (Eleanor protects little sisters, Corvo protects Emily, Both have super natural abilities one that is magic, the other that is consumed.)

Chimeran Hybrid vs Necropmorph.

My questions are do you think those new match ups are better? and do you think I have enough to work with to make Necromorph an actual fighter and good rival for Chimera Hybrid and if not who should I choose? Super Mutant or Faux (Fallout), Darkspawn (Dragon Age), Crypto (Destroy All Humans), Alex Mercer (Prototype), or Domasi Tawodi aka "Tommy" (Prey). Also who would you have be the rivals to these characters?
