Use Standby DB instead of Primary DB

Question

Hi,
I've a plan let's assume Data Guard has been set successfully with the following condition:
Primary:
DB_NAME=DB1
DB_UNIQUE_NAME=DB1
Secondary:
DB_NAME=DB1
DB_UNIQUE_NAME=DB2
After a couple of days, I switchover DB2 become primary and DB1 is secondary. Then I want completely use DB2 as single instance, throw away DB1.
It's mean DB_NAME and DB_UNIQUE_NAME will be different like this:
Primary:
DB_NAME=DB1
DB_UNIQUE_NAME=DB2
Later I want reconfigure Data Guard with the new standby DB, called DB3.
Since this DB is not 'pure' primary and DB_NAME is different with DB_UNIQUE_NAME, is it okay for this database go production as primary ?
Need your advice please,
Oracle version : 11gR2 for AIX 6.1 (64bit)
Thank you,
Yusata.

You may set DB_NAME=TEST, at 1st instance db_unique_name=test_inst1, at 2nd - db_unique_name=test_inst2, for example.
Normally both db are equal, they just switch their roles.
