How can I raise the possibilty here(after "I mean")?

I decided to choose an interesting subject, I mean a topic that you are really interesed in.

What’s the correct procedure in cases like this? What's the rational choice?

1. "... I mean a topic that you might/may really interested in?

2. "... I mean a topic that you would probably interested in.

3. "... I mean a topic that you are probably interested in.

4. Or what else can I say...?

I would like to know whether the repeated usage of the expressions "interesting" and "interested in" sounds a little weird and awkward or not.

Does the simultaneous usage of the two above-mentioned expressions with the root "interest" show the speaker's lexical weakness?

Is there anything you’d like to add or change?
