Covered California (Obamacare) question

[johnny_in_CA]

We have a weird situation. My employer offers me full medical/dental/vision coverage (100% premium paid by employer). I recently got married, and while my wife can be covered as a dependent, my employer will not pay any of her premium. Her portion of the premium can come out pre-pax from my paycheck. 

However, my HR and the insurance broker they use have onerous requirements to on-board her. Without going into unnecessary details, we think it might be cost-neutral and less tiresome for us to simply buy an appropriate level of coverage from the Covered California (Obamacare) exchanges.

My questions for the experts are:

1. Is there anything stopping us from doing this? (i.e., the fact that I could put up with the hassle and have her covered, that an employer is, in theory, willing to offer her coverage, etc).

2. Since I  can't pay her new premium pre-tax from my paycheck, is there a way to regain the tax advantage later on, by reporting the amount off a 1095-A?

3.  Any tips, cautions you're willing to offer. 

Many thanks in advance.
