Re: Omitting if in conditional sentences,
You can doubt whether something is right; you can doubt whether something is wrong; you cannot doubt whether something is wrong or right.

However, this is not common, and sounds formal/old-fashioned. Inversion (with or without DO) is not possible with other verbs.
Did I have enough money, I would buy that car.
Do I have enough money, I will buy that car.
This is possible in third conditional sentences.
Had I had enough money, I would have bought that car.
