My experience is limited, but I had to do multiple re-pottings on a cattleya not too long ago. This cat was visiting me and it knocked the poor orchid down and out of its pot TWICE within 2 days. I had to re-pot again a THIRD time a week later because I put the plant too far down into the container and I was worried about rotting.

Anyway, after the last re-potting, the plant got pretty healthy again...the shriveled bulbs have gradually come back and are nice and healthy, and there is a new bulb and leaves growing, so I extremely stoked.

If I were you, I would just bite the bullet and re-pot right away. It sounds like you have a nice, well-drained pot in mind. Your leaves are healthy and green, so I don't think your plant will get shocked all that much. It will probably take it a week or two to get used to its new surroundings, but the turnaround will be pretty quick, and you and the plant will be much happier within a month...rather than having this constant doubt and worry in the back of your mind like I did.
