Can you do that, while files are open?

i.e. can you say to the kernel  "I have a whole lot of files currently
open on this partition; please keep the file handles open, but forget
the encryption key NOW; when an application next wants to read or write
them, block the application, and pop up a prompt to ask for my passphrase"


If so, I'd love to know.
