Langtags
Lingua Libre uses nor ISO 639-3 nor BCP47 but Wikidata Qids as internal identifier for a language. Currently, ISO639-3 codes are used in two cases:
• For the name of pages containing lists in the list namespace (in the format , with ISO the iso6369-3 code);
• To forge Wikimedia Commons's category names

Switching to other code ?
Changing the code would affect only those two parts of the process. If we switch from one language tag to an other, we would have to:
- Add a new property BCP47 locally as you suggested (a bot can import them from Wikidata);
- Rename all local lists (can be made by hand, we don't have many lists for now on);
- Rename all existing Wikimedia Commons categories and move all the audio recordings (a bot there is required);
Other notable codes
- BCP47 - prefered langtag in computational fields
