Honestly with the web APIs it could even be possible to use a live translation service, but only if the right web service exists and those automatic translations can be so hit or miss.

DeepL for example has cURL and HTTP request: https://www.deepl.com/docs-api
Coming back to the question, yes tooltips are possible in general, the "issue" would be hard linking the provided translation, very cumbersome work.
Somehting like hooking into a live service as @bmos said would be way easier to handle (for everyone involved)
Crowdin also exists :)
