Since you apparently are on SQL 2005, I have a better idea: synonyms.

CREATE SYNONYM LogTable FOR databaseB.dbo.LogTable

and you are done.

Using the transaction log would require that you have a log reader
like Lumigent's Log Explorer to read the log. But since would be a one-
off, it seems to me that you could use a trigger to pick up the changes
while the copy is running.
