In theory, it's possible to run fw_all.bin by using it as boot.bin in gupdate.gcd file. This would allow testing patched firmwares without saving them to flash, and therefore, without being afraid to brick the device.
But I'm not sure it would work, as fw_all.bin is much larger than boot.bin.
So I packed a slightly patched fw_all.bin (US v4.60 HWID 504) with gfwpack and created the following two gupdate.gcd files for HWIDs 265 and 504:

Is anyone willing to test if flashing one of the gupdate.gcd files successfully executes the patched firmware inside?
If fw_all.bin runs normally, then you would see that all the displayed strings were replaced with "X".
