Additional training != new type rating. Additional training may just be a couple hours of instruction. A new type rating would involve both ground school instruction and dozens of hours in a sim. It'd probably take a couple weeks to get a single pilot a new type rating.

However, the bottleneck is that there aren't very many sims worldwide, and most are owned by airlines that don't exactly have an incentive to get pilots other than their own trained.
