High Sodium/Higher Potassium - Good thing?

Hey all,

Wondering if anyone knows, or has read anything about high sodium/high potassium diets? That being, a diet in which one consumes high amounts of sodium (likely 2000-4000mg) and high potassium (likely 3000-6000mg) per day. There have been definite links between a poor sodium/potassium ratio and things like high blood pressure, but nothing I could find suggested whether or not you could combat a high sodium diet using a high potassium diet. Any ideas from dieticians/medical professionals, or studies on the topic that anyone has found would be awesome.
