Can, but probably not. It's a mod of fo4, and if it's free and all the content is recreated by the team(meaning no using fo2 asset like voice line), it should be getting a pass.
And then the Fallout 4 Capital Wasteland team that's been remaking the DLCs and main game of Fallout 3.
Then there's the Fallout 4 New Vegas team, which has been doing the same but for New Vegas.
Then there's the Fallout 2 remaster team mentioned in this article (Project Arroyo).
And then there's the Fallout 1 remaster team (Project Vault 13).
There's also mods being developed that are entirely new areas, such as Fallout London, Fallout Miami, and Fallout Cascadia.
Along with the Elder Scrolls equivalents of Beyond Skyrim's teams, Nirn Uncharted, and Apotheosis, which aims to have all the daedric realms.
Despite any blunders Bethesda might have made, their modding community is thriving now better than ever.
Edit: Also all of these projects have Discord servers where they post regular progress updates.
