That won't work, because each iPhone has a unique ID that's part of the SoC. Trying to extract that would require removing the A5 SoC used in the 5c, decapping it and using an electron microscope to determine the unique ID (assuming you know where to look the die, which may require Apple's help)

The passwords can only be tried on the original phone, they can't copy the data elsewhere to an emulator unless they can get at that unique ID.

Maybe that's what the Israeli firm did, but if so that raises the cost an order of magnitude due to the extremely expensive equipment required, though at least it would be quick. But still, only useful for phones using a PIN, if you use a password you'd be fine so long as it isn't susceptible to a dictionary attack (so don't use "password"!)
