Just wait until the oil drips on to your discs! Thats an even more interesting scenario!
When I was a callow youth I used to drain all the oil out when this happened and carry on riding
However it's much better to sort it. I'm a mechanical muppet and I've changed the seals in the past, but only on right way up forks. What you have to check out first is why the fork seals have failed. It could just be old age or it could be that there is rust or pitting of the stanchion.
Are you near a ducati dealer or a mechanic you can trust? I wouldn't have thought it would cost more than an hour or max two hours labour plus the cost of the seals.
