Your original suggestion has no solution either :-)

Unreadable. I think we could create a hash of the directory part and append 
it to the basename eg typo3temp/js/basemame_HASH.js. Or we could create 
really long names by using the "full path" and replace all /'s with _'s or 
-'s. eg typo3temp/js/typo3-tree.js

No. When a minimize file is not found it will simply be created.

Yes to the general idea. But I think we have no quite a number of caches in 
different places and it's getting hard for me to understand when which 
cache is cleared.
