Steve,

I think that's going to be a problem. If you don't recover to a point in time after the backup completed, some of the data is going to be inconsistent. If any data changed in the not-yet-backed-up datafiles after your target PIT but before the backup completed, those changed blocks will be from a time ahead of your target PIT.

You can open the database inconsistent using _allow_resetlogs_corruption, but that's only for in a pinch. With that option, the data may be internally inconsistent, and you can also get ORA-00600 and ORA-07445 errors in the opened database. Also the resulting database is unsupportable.

There are plenty of notes on using this parameter out in the public domain.
