No, you still need to run another process.
In the beginning, there was a PC application included in the distribution called fixelf.exe to inject that elf file to the 0000000c.app (taken from decrypting MIOSv10 WAD content).
Now, you could do a similar approach, but you need to use 00000001.app taken from decrypting DIOSMIOS WAD content. And you need to use the modified version of fixelf, called
fixelfmod.exe.
In case you want to try playing with DIOSMIOS codes:
For real nand user, the command to use fixelfmod is
fixelfmod 00000001.app diosmiosfile.elf temp.app
then rename the temp.app file to 00000001.app for replacing the one in the DIOSMIOS WAD folder and then pack
the WAD back for testing (and accepting the risk of installing WAD to your NAND).
Hope that helps.
