It's not possible. Light would have to bend up and then keep bending up, but this doesn't happen. FET assumes the laws of physics are significantly different for us than the heavens, somehow. The uniformity of nature is one of the most powerful tools a scientist can be blessed with, and theories that assume different laws for us down here on earth tend to be wrong.
Also, how does something like "my gut feeling is that it's electromagnetic acceleration" compare to general relativity?
