Aren't we looking for trouble with this scenario? What if you hold lock for more than few seconds/minutes/hours? I'd ask following questions ...
1. Why?
2. Why?
AFAIK one way to do this is to break the synonym pointing to the database, but any other code owned by the same schema will continue to look at a read consistent image of the table. Also by breaking the synonym, you risk having invalid code in the database and it is a cascading effect...
Seriously, I'd find why your user would like to do this.
