I came across the dialog and was puzzling over the sentence "したことのないことばかり"

> （中野さんと大和さんがおみあいをしています。）
>
> 中野：大和さんは、お休みの日はなにをされていますか。
>
> 大和：ゴルフをしたり美術館を見学したりして、それに絵を書いたり裁縫したりするのです。
>
> 中野：わあ、すごいですね。
>
> 大和：中野さんは？
>
> 中野：私は、パチンコやカラオケをしたりして、時々軽くお酒を飲むのも好きです。
>
> 大和：フフフ、 **私がしたことのないことばかり** です。面白いでしょうね。

I think I understand bold part, but is it possible that 大和 replies this
sentence instead?

> 大和：フフフ、 **私がしなかったことばかり** です。面白いでしょうね。

Is there any change in meaning compared to the original sentence?

(The reason why I ask such question is because I think the original sentence
uses two "こと", won't that be a little bit redundant?)

Question about "したことのないことばかり"
The meaning is quite different. Roughly:

私がしたことのないことばかりです - Those are things I've never tried doing.

vs

私がしなかったことばかりです - Those are things I never did.

The second sentence leaves the impression that the speaker wanted or was
supposed to do those things at some point.

The first sentence is just saying that the speaker have never done those
things in his life.

Two こと are not redundant, as they refer to different verbs (したこと and ないこと).

answer
I will start by briefly explaining what 「お見合{みあ}い」 is for those unfamiliar
with the custom and/or the term. It is a formal kind of meeting for a man and
woman with a view to marriage. The conversation above is taking place at such
a meeting.

From the convo, 中野{なかの} is the man and 大和{やまと}, the woman. As anyone would
expect, "hobbies" is a common topic at お見合い and that is exactly what is being
talked about here.

As seen in the convo, however, the two people might not share a favorite
pastime. So, the woman says:

> 「私がした **こと** のない **こと** ばかりです。」
>
> = "I have no experience in doing any of those things."

This is said upon finding out what the man's hobbies are.

_**The first こと means "experience" (～ことがある/～ことがない) and the second こと means
"things".**_ Thus, using こと twice is not at all redundant. The sentence is
perfectly correct and natural-sounding.

Finally, could 大和 have instead said:

> 「私が **しなかった** ことばかりです。」?

No, no chance at all. Why not?

The two are discussing their **hobbies**. They are not discussing the actions
they performed on a particular occasion in the past. They are talking about
what they like to do **habitually**. This is why you cannot use the past tense
「した」 or 「しなかった」. Hope you are following this logic.

Let us suppose that you went to Hawaii last year and I went there just
recently and we are talking about what we did while in Hawaii. You did
activities A, B, C and D and I did X, Y and Z.

Upon finding out about what I did, you might say:

> 「私がしなかったことばかりです。」
>
> = "I didn't do any of those things." Or more literally, "All of those are
> the things that I didn't do."

That will be a very natural reply.
