In general, domain knowledge is incredibly valuable and will generally trump someone who may have some more technical skills but doesn't know the field. I'd add that a lot of larger companies--heard someone from Shell talking about this a couple months ago--are training up people who have knowledge of the business with "citizen data scientist" skill sets.
Without knowing all the details of your situation, it seems at least a much lower risk path to acquire some data science skills--maybe your company will even pay for it--that you can pair with your existing domain knowledge.
