Storage Library location

On the MDBT42 currently I use Flash (for a circular logging buffer where some bytes are written twice before erase) and FlashEEPROM for storing a couple of params. I make sure they don't overlap by doing the following:

flashEEPROM = new (require("FlashEEPROM"))();
flashEEPROM.endAddr = flashEEPROM.addr+PAGE_SIZE;
  
flash = require("Flash");
logStartAddress = flashEEPROM.endAddr;
logEndAddress = logStartAddress + NUM_LOG_PAGES*PAGE_SIZE;

I am interested in swapping out flashEEPROM for the new Storage Library as want to store downloaded code to run and it seems a nice way to handle it. Can I get it to run alongside the Flash library ? If not I will just use the Flash lib to store the code.
