Not really, because Org would no longer un-escape the URI. This could
work for links opened with a browser, but not for other types (e.g.,
a target).

This one is already possible, isn't it? Also, I suggest to change
brackets links, not plain links.

Yes, those would become valid. The following regexp could be used as
a replacement for `org-bracket-link-regexp'

  "\\[\\[[^]+?\\(\\]\\[[^]]\\)?\\]\\]"

or, with groups,

  "\\[\\[\\([^]+?\\)\\(?:\\]\\[\\([^]+?\\)\\)?\\]\\]"
