Hi

I think that for Time Machine to backup contents of File Vault  
incrementally by file it would not present a problem for security.

It would need to be that when File Vault is opened on the Mac, then  
Time Machine would open its copy.

Remember that the disc image will "unmount" as soon as the OS is shut  
down, logged out, or if the external hard-drive is disconnected, it is  
not like a folder in that regard. So there would be no risk of the  
Time Machine copy of File Vault remaining open in some way.
