First version has a minor grammar error:

... and allow*s* you ...

Apart from that, both are fine. I would probably use the second version.

I think both sentences are too similiar to use in the same paragraph.

My short answer: Either is fine. I'd probably use the version with two "will"s because the sentence is long enough that with only one the implied "re-use" of the first one could get lost.
It is true that in general one should be cautious about using the same word twice in one sentence. But that guideline is less important when talking about short common words, like "is" and "he" and "the" ... and "will".
In a very short sentence, it's common to drop the second "will" on a compound future-tense verb.

Fine: Sally will stand and will give her speech.
Better: Sally will stand and give her speech.

The second is correct because the "will" is understood to apply to both "stand" and "give". It is better because it avoids saying "will" twice in rapid succession.
But in your example, "expand" and "allow" are pretty far apart, and it is easier to see a reader losing track of that first "will". In that case not dropping the second "will" may make the sentence more clear.

I would choose the first option over the second. That said, @Stephen has a point. If you include the "s" as he suggests, you will put the verb in present tense, if you leave off the "s", it will be a future tense verb which would likely be preferred.

Try to avoid using "will" twice, it makes the sentence flow better.

Here is a link to an english.se question relating your question.

This answer is assuming that the OP's intended question was "Can I use will two times in the same sentence?" rather than "Can I use will two times in the same paragraph?"
