Possible to flare hard brake line?

[rhock99 at epix.net (Ryan H)]

I'm thinking about cutting the hard line right below the nut (can't get it off).  Would it be possible just to put a new nut on the cut line, then flare the end and just bend the line an extra 1/2" to make up for the cut-off length?
I haven't been able to remove any of these to see how it is even flared.  Any help appreciated!
Thanks.
