It could have been possible after 2005 (when i386 patents expired) but then, it was hard to compete with Intel's process advantage and financial maneuvering to squash competition. Intel is in a more vulnerable spot today when many more companies have access to more advanced processes through TSMC and Samsung as well as in-house expertise in general CPU implementation.
