You could write a script that creates the second data group after any changes have been made to the first data group. You'd probably want to run the script from cron or as an external monitor. You could check to see if the modify time of the first data group has changed since the last script runtime. Or you could modify whatever process you're using to set the first data group to also update the second one.
The performance of an internal and external data group should be identical as they're both loaded into TMM memory.
