Something similar has been done over 30 years ago, see

The module is called BACKRAM, and you are supposed to load the contents 
with RAM_LOADER.PRG. We use the COMBIROM file that has many very useful 
routines for tape and CBM disk handling. I've attached a CBM 8050 drive to 
the Tektronix 4051. To use the BACKRAM I only need one tape cartridge that 
holds the loader and RAM image.
