it is possible if you get enough time to think of every word, you just need to to find synonims so you don't write specific letters, often needing to switch both words/speech style
(it's very difficult though, I've been writing this comment for 5 to 10 minutes)
Definitely unneeded. The ending letter of the series of letters we employ to form words is especially useless, but to be honest the first is mostly superfluous too
