I was hoping to enable write back with the use of a battery backed
ramdisk. I'm simply substituting the SSD for a physical ramdisk. The
ramdisk would outperform the SSD and would probably be safer during
power loss than a SSD (assuming the battery is in good condition).

It'd function, but performance would be worse than just using the
pagecache, bcache does a whole lot of extra work to get around the
limitations of SSDs and the pagecache is blazing fast. Why would you
want to do that?
