There is another solution which can be done entirely by RMAN, without the need for the big endian/little endian mess:

You can use Linux on Power systems which would bring you to the desired OS. In my opinion, the architecture of the IBM

Power systems is superior to the architecture any x86_64 based systems, especially when it comes to IO. There is also something called "Blue Cloud" and IBM can help you with moving your Oracle databases to the x86_64 based systems in the Blue Cloud. You know that Red Hat is owned by IBM? Later versions of AIX are extremely similar to Linux. The last one with which I have some experience is AIX 7.2. It has bash, less, GNU tools, strace and /proc file system.  This would look a lot like Linux if it wasn't for the AIX kernel, different parameters and SMIT. I was always annoyed by "topas" on AIX systems instead of "top" which is found on all other operating systems. IBM did a fair amount of porting themselves: Nigel's monitor ("nmon") is available on Linux and so are JFS and GPFS, the last one being a commercial product which must be licensed.
