Kameko and Kamiko - Part 2 - Special rules idea

As mentioned in the previous post about these Japanese exchange students, I wanted to have some special rule for the pair of them.

 An idea came to me while watching an episode of "The Walking Dead".

Kameko and Kamiko special rule: as long as the twins are in close distance to each other (say within 2") each gains the other's primary attack  during the turn. Thus, Kameko gains a ranged attack with a pistol using Kamiko's weapon and skill rating, and Kamiko gains Kameko's melee attack with a sword and skill rating.

 This give you two ranged attacks or two melee attacks for the twins instead of one of each.

 If they are out of the 2" range from each other, then they loose this special ability.
