Theoretically you can use System.normalize() and System.get() to lookup a module by name synchronously. The normalize feature requires a referrer or address. Since browsers are determined to eliminate synchronous scripts, you may as well deal with the asynchronous System.import() and obnoxious promises stuff now and save yourself some pain later.
