Use of the word "o"

Use of the word "o"
 

I'm wondering about the distributive property of prepositions and pronouns with the word "o". (I suppose it applies to "y" as well.)

Let's take this sentence:

Si en tu cuadra, en tu barrio, en tu unidad o en tu universidad están organizando algún evento y quieres que la ciudad lo sepa, cuéntanos.

I'd like to omit the second, third, and fourth iterations of the word "en" in this sentence, like so:

Si en tu cuadra, tu barrio, tu unidad o tu universidad están organizando algún evento y quieres que la ciudad lo sepa, cuéntanos.

Can I do that?

Further, can I omit the second, third, and fourth iterations of the word "tu?

Si en tu cuadra, barrio, unidad o universidad están organizando algún evento y quieres que la ciudad lo sepa, cuéntanos.

Thanks in advance!

This is the way to say it. Spanish hate redundancies. I would rather use "se está". Not sure what you mean by "unidad" because in that context it only sounds military to me.

Thank you for your reply.

I saw the long version of the sentence on the front page of a Spanish-language daily. I often see and hear such redundancies, and to me they sound ugly. I think the only good use for such repetition is emphasis.

"Unidad" here must be an "unidad habitacional"; these are usually closed clusters of houses or appartment buildings. That's how it is understood in Mexico anyway.
