It's unclear if you're talking about using a single large block cypher,
but assuming yes..

It's unclear what you're protecting against.  I'd recommend reading Ross
Anderson's The Dancing Bear :
http://cs.uccs.edu/~cs591/securityEngineering/grizzle.pdf

You could likely achieve whatever you want with either some grizzle
construction, or maybe some fixed none, mac, etc. encrypted along with
the plain text.
