Using DG to upgrade from 11.2.0.3 (on RHEL 6.10) to 18c (on RHEL 7.5)

I've read a few postings on a similar question, but none of them have mentioned MOS 785347.1
I would like to use dataguard to create a 18c standby database for an 11.2.0.3 primary DB in order to accomplish two things:
(1) Upgrade the 11.2.0.3 database to 18c
(2) Go from RHEL 6.10 to RHEL 7.5
We have a tight window to do this upgrade, so having a standby ready for upgrade would greatly reduce our downtime (the 11.2.0.3 DB is 10TB in size). A major stumbling block is the fact that 11.2.0.3 is not supported on RHEL 7.5, otherwise I would create the standby as an 11.2.0.3 database, install the 18C binaries on the standby host and upgrade the DB as per normal.
