I think the biggest problem is that if you type "reiwa" in an IME, 令和 wouldn't be shown as a suggestion because it wasn't a real word before. You'd have to write each character separately.

Also speaking of Abe I saw a joke that you could see アベ in the era name if you look closely. http://livedoor.blogimg.jp/animanmatome/imgs/5/f/5fa3bffe-s....
