If you said that, no one would understand. One possibility (a lot wordier) would be to say "Sorry, I really don't want to hurt your feelings, but this just isn't to my taste."

War nur ein Beispiel.
Kann man sagen pace you für ich will dir nict zu nahe treten?

No. In my experience, I have only seen "pace" written; I have never heard it spoken. (I didn't even know the way it is supposed to be pronounced until a few hours ago when I looked it up.)

The dictionary offers a good substitute: "With all due respect." Use that instead of "pace".

"peace"

Suggestion

Could it be the Italian "pace". I have an Italian friend who uses this word, sort of in the sense of "don't get me wrong".

I also have never heard "pace" used like that. Wer weiss. Maybe it's regional.
I'd say:
-- Don't take that personally.
-- No offence intended.

pace
PRONUNCIATION:
(PAY-see, PAH-chay, PAH-kay)

MEANING:
With due respect to. (used to express polite disagreement)

ETYMOLOGY:
From Latin pace (in peace), from pax (peace). Ultimately from the Indo-European root pag-/pak- (to fasten) that is also the source of peace, pacify, pact, travel, compact, pagan, and peasant.

USAGE:
"The movie Scoop (pace my friend and occasional critical contributor to this page who reviewed it favorably) is merely another mark of Woody Allen's descent into insubstantiality."

"pace" is a preposition, another reason why you can't say "pace you".

Well, it's a preposition that means something like 'in spite of,' so you can see why someone might wonder if it would work. But it isn't used with pronouns, or normally in conversation at all; see the thread linked above for examples, which are mostly from rather formal writing.
