Would it make sense to create a new instance to use an existing forums structure for downloads?

I’m really liking the worth RetroMags is doing, and notice they have 16K members, so I assume it’s about 4K active monthly users.

I’m wondering if to expand both their users, and the fedizerse’s users, if it would make any sense at all to use the servers they use for downloads on a new Lemmy instance, that creates a seperate community for each magazine, and auto populates a new post in the correct community every time they post a new download over on their forums.

They don’t REQUIRE membership to download, which is what this whole idea is based on. Since I assume it would be entirely too costly to have downloads on their forums AND a duplicate set of downloads on a seperate server. Seems costly given their massive scale.

Am I dreaming pipe-dreams? Or should I let them know about this idea?
