I don’t know if RIF was exposing that underlying functionality, but Reddit had native support for that in the Web UI. It was called a multireddit, could “merge” the contents of multiple subreddits.
Reddit also had native support for ad-hoc merged views of subreddits. You could do multiple subreddits combined with a “+”, and Reddit would create a view with posts from both.
I never got much out of either functionality myself. The latter feature I saw mostly used by people creating “mega porn views” that merged many different NSFW subreddits.
A client could theoretically do that here at the client level, but AFAIK there’s no comparable server-side support.
