{SeQpIr Daleghchu'be'pu', mung tlhIngan HolDajDaq ghaH DalaDpu'pa'.}

Since klingon vocabulary is perceived to be the literal and not
metaphoric meaning of its word,

That's not right. Idioms often don't translate between languages, and since Klingon is unrelated to any Earth language there's no chance that idioms in one are also idioms in the other (unless there's borrowing). But Klingon can employ metaphors just fine, and KGT gives us a whole host of idioms, similes, and slang.

 I don't think that {legh} can be used
to express "experience" as in "I experience SeQpIr". Reading this part
of the sentence would make me understand "you haven't seen SeQpIr in
the flesh unless..".

I agree that mixing seeing Shakespeare and reading Shakespeare is inappropriate. Someone else suggested SIQ endure, and in this case that might be a good choice.

The costruction {mung tlhIngan HolDajDaq} has two problems:

1. The literal translation is "at his klingon language of origin",
which I'm not quite sure it sounds well/nice. Of course, this might be
just a matter of personal preference. However, I would rather go with
{tlhIngan Hol wa'DIch}. Since in Klingon monopoly we have {Quj
wa'DIch} to refer to the original monopoly game, then I believe it
would fit here too, quite nicely.

Actually, mung tlhIngan Hol means origin Klingon, which does not mean original Klingon. I'm not sure I know what it really means. I wouldn't choose tlhIngan Hol wa'DIch first Klingon for this either. I'd employ a verb for this, something like qonDI' tlhIngan Hol lo' when he wrote it he used Klingon.

2. And this is the major problem. The {-Daq} can only be used to refer
to physical locations. If you would like to use it anyway, perhaps you
could say something like {tlhIngan wa'DIch ghItlhDaq} for "at the
manuscript of the original klingon".

This is correct.

Jeremy Silver:

{SeQpIr Daleghchu' neH, mung tlhIngan HolDajDaq ghaH DalaDDI'.}

The problem here is that when we use {neH} on a verb, the meaning
isn't "only". The meaning is "merely". So, the meaning here would be
"you will merely see perfectly SeQpIr", and not "you will only see
perfectly SeQpIr".
