If I were you, I would help her.
I know the sentence above can be inversed as: Were I you, I would help her.
But what about this: If I had enough money, I would travel around the world.
How to inverse the sentence?
My answer is: Did I have enough money, I would travel around the world. Is that correct? Sounds rather strange to me
One of the most famous English poems begins 'Had we but world enough, and time,' so it can be done, but in your example there doesn't seem to be a great need for the inversion, which makes it sound strange. If you change it to 'Had I the money', it sounds better to me.
