Love the idea, but I'm wondering if the backend could leverage one of the fediverse technologies?

For example when someone comments or upvotes a page, a post for that page is automatically created on a Lemmy instance, and that will be used to manage the comments and upvotes.

That way you don't need a server backend and you take advantage of a decentralised architecture

Aren't you centralizing on Lemmy?

Lemmy is decentralised so... no?

But using one instance to handle voting/replies means it's centralized (everything happens in one place).

Lemmy doesn't allow someone to edit content from different instances so that aspect isn't decentralized. If I make a post on one instance the post could be shared within the federation which makes that feature decentralized. At best Lemmy is a hybrid decentralized-centralized application.
