I did it with a two-step for the above reason. The modification required the removal of the original brackets which increased the first step drop by 2 inches, which led to the first step being "a doozy", and also just wasn't able to mount the new steps anyway.
The first step came down to 8", iirc, and the second step was 9" - maybe it was the other way around ? The final drop from stairs to ground was 4-5". So obviously an issue with the steps not being equal. However it was still safer than the original high wire act. When I sold the trailer last year, I just happened to have the original stairs and gave them to the new owner who intended to put them back on. I don't know how well that worked out.
I am VERY happy with the stairs in our new Venture Sonic - instead of being mounted below the frame, these are mounted inside the doorway and swing down once the door is open. Very substantial 2 step model, very stable. Youtube has walk-through videos that show these steps, which I am sure could be sourced. You may need to install a whole new door, however.
