That's a good idea, that was one of the best 3rd edition adventures made/ Hell, it's one of the better D&D adventures period. But no, I don't have stats for it.
It's not really that hard to use most previous edition adventures here in 5e.
You open the MM/Volo's to the appropriate page & use the 5e stats for whatever monster.
Make up stats for anything not yet in 5e. (Often I'll just copy/paste the bits from the previous stat block that I'll need)
Treasure? Adjust it as you see fit.
I'm converting it now. First session on April 7th! It's pretty much a 1:1 conversion so far and I'm most of the way through Part One. I did change the monster at Blackwater Causeway to something else though since my players recently faced a hydra in the last campaign.
