Removing localized versions of a website. What should i take in mind?

I want to delete some localized versions of my website. Let's say .com/pt, .com/es, .com/fi and .com/it The international version is about 2000 pages long. However, these localizations are about 50ish pages each. They do have a lot of referring domains pointing to them (backlinks). What is the best practice? Redirect those pages to the default language counterpart. Or just point them to the homepage? Is creating a lot of redirects at once a bad thing? I assume adding around 250ish 301 redirects should not be optimal? Apart from internal links and broken pages that might appear, is there something else I should take in mind or do? Cheers!
