I trimmed my large Thoth specifically to remove the keywords. But I wasn't really the person who had trouble with the keywords...people who I read for did. Of course, I have only read online, and here at the forum, but once someone knows that "Failure" is on the table, they cannot get past it. So if I do any readings in person with the Thoth, I will be using my trimmed one.
If necessary, I would have no problem trimming another deck.
I don't think I would have a problem if I couldn't tell what card was what. I don't use books or others' meanings for the cards so what they are isn't as important as what they mean in the context of the reading. Frequently what I find the cards to mean isn't what any author or even the creator of the deck identifies as its meaning anyway.
One recommendation I have regarding trimming though - use a trimmer and trim to make the cards the same size. Sometimes following the printed border can cause the cards to be different sizes and makes them difficult to shuffle. I noticed during my Thoth trim that some of the borders were different sizes - so when I trimmed just based on the border lines, the cards didn't come out the same size.
