You're right. You said replica. Them your words.
Vikings made use of the land available at the time, and the castle. It was then integrated into Bermuda because it was already there and removing it was stupid.
If Skyway was still standing in it's original install configuration, I couldn't call it terrible - it's better than no skyway at all. They've done zero worthy alterations to the land the skyway occupied. So skyway wasn't terrible. I wouldn't advocate for them to bring it back in the same configuration. Nor would I ask them to do that with Log Flume (although it has been said that the trough is most likely in reasonable condition and all it would need is new boats which is a damn sight cheaper than building a whole new log flume from scratch.)
Pirate was meh. it was good because it didn't invert and that let the more easily intimidated visitors give a swinging ship a try without worrying about the 'upside down' part like Bounty's revenge always had. I'd like for them to install a modern ride of similar experience - take a look at Luna Park Sydney's new lineup for some inspirations.
Bottom line - if all three of those attractions still operated today in their 'of the time' configuration, I wouldn't be upset. None of their footprints have been taken over by any new installation, and they could coexist happily in the parks line-up which would, overall, improve a guest's experience simply by volume alone.
BUT since all of them HAVE been removed, they should bring a modern simile to the park that offers a similar ride type or experience, but with improvements or advancements on the tech of the 80s to keep current with today's trends and systems.
