Excluding a column with snapshot replication

I have a database that I'm trying to replicate to allow users to run MI
type queries. This would remove the impact on the operational database
of long running expensive queries. The database records details of
emails including the text and is about 40 GB in size. The database is
part of a package system. One table contains all the text of all emails
in an ntext column and accounts for 25 GB. I would like to exclude the
column from replication as with it, replication takes over 12 hours and
the MI queries do not use the column. However, the queries do use views
that reference the column.
I'm using snapshot replication that runs once a day. In the
"Publication Properties" in the "Filter Columns" tab, I de-selected the
column. The target database has an identical schema to the source
database. When the distribution job runs it fails with a message
indicating it couldn't bulk load the table in question and the error
message indicates that an "Unexpected EOF encountered in BCP data-file".
I've assumed that the BCP data file has a structure that is at
variance with the table. I tried dropping the column from the target
table but replication then fails during the application of a number of
*View.sch scripts because the views reference the column. This is
despite the fact that the publication property for all database objects
is not to drop them.
Can anyone suggest a way in which I can get replication to work without
including the data in one column but to retain the complete schema.
TIA

Laurence,
you could replicate the table (minus the problem column) to a table of
another name. Create a view which has the old tablename and queries the new
table, with an additional column containing a hardcoded null.

This has done the trick.
