The issue is because strings are designed for a very narrow string tension, otherwise all strings would be the same thickness and the same materials. A high guitar E is thin and often plain steel (electric) because it is under lots of pressure and it is a high pitch instrument. Tuning it down lowers the tension and thus it is flabby. Tuning it up makes it tighter, harder to play and can potentially break the string. It's all just Physics. At least with violins, they make some alternate tuning strings, you might want to search by those terms to see if such a thing exists for the guitar.
