Active status effect dynamics

[(PSN)Dragulish]

So as the elemental effects are now have been perfect to me thus far but I recently had an idea on how to better synergize it. 

Applying cold and toxic as we know creates viral damage to a weapon but sometimes for the maximum effectiveness and damage I would like to apply cold without pooling all my effects and mod slots into toxin for the viral effect which takes away from cold damage but I would also like to be able to add that effect by choice. 

 

For a better, less muddled example of what I want to see 

I build a damage+ cold+ speed weapon and decide to carry pox full toxin build, I want to be able to stab an enemy and proc cold and throw a pox blade and see them now take viral damage if cold status is still active when toxic procs.
