That is exactly what the firmware-independent simpleImage.initrd.* targets already do. The resulting elf file include the dtb and initrd as well as a prompt-like boot arg cli. I think it will be possible to just place the simpleImage.initrd.* into you memory and let the existing code jump to the start adress of the elf image. I managed to start a ppc core using JTAG and the simpleImage.initrd elf files and I think the procedure is very much the same but instead of the JTAG debugger setting the PC to the start address, your startup code has to do it.
