Hmm! I felt a bit restless and planned to write it as a full adventure but with everything adapted for Classic Fantasy.
But I downloaded the conversion in the link you posted and doing it that way would actually save me a lot of work making a conversion document like that with new stat blocks and a skill translation list.
Have plans of getting more of your adventures (since I like that they are so generic and can be put into almost any campaign world) and do similar conversions since I know the Classic Fantasy community are growing and craving some ready made adventures.
I am pretty sure Chaosium wouldn't mind putting up conversion documents for your adventures either.
