SWAP Equipment using IE4N, without serial number and material, it is possible?

Question

Hi PM Experts, I´ve been reading about the way to SWAP equipments from his functional location without using serial number and material, I think if it is not possible, but to be honest, I cannot find any logical answer for it, since equipment number is unique for a plant. Does anyone have found any work around for it?.
I don’t want to use serial numbers and materials, because I think the process is really simple, since the client does not want to implement the refurbishment process. If there is a break down, here is what I do:
Case 1:
Dismantle damage equipment (Say PM01 Order Type)
Install new equipment (same PM order)
TECO the actual PM order
...Later
Case 2:
Create a new PM orden (say PM01 Order Type)
Repair the break equipment
TECO this new PM Order
Here are the inconsistencies:
What happen with the MTTR and MTBR reports?
In case one, I´ll create the material as equipment, while I´m installing, starting date for his master data is the installation day, and the MTTR and MTBR will start to run. This is ok.
What happened in case 2?, I need to stop the “clock” for the MTTR and MTBR of the dismantle equipment.
This is the reason why, I would like to use IE4N, but since there are no serial number and material, I cannot.
Can anyone please suggest a workaround for this scenario?.
I´m thinking in use INAC (Object Deactivated) system status, can this status help me?, Does this status “stops” the clock for MTTR and MTBR report?. If I change the status to ACT, I´ll get the clock back running?.
How about dismantle the equipment?, It will get the AVLB Available status, but the problem is, this equipment will be “floating” in the whole PM structure and I do not want it. I want to have it in a specific Functional Location but with this status, is this possible?. I woul like to use IE4N to SWAP UTs and later change the status to AVLB Available status, with and exits.
I thinking in an Equipment Status and a “Z” MTTR and MTBR report, based on this status. But to be honest, I´d like a standard solution for it.

For find my iPhone to work, the device has to be powered on and it has to be connected to a network (Cellular or WiFi).  Find My iPhone uses your AppleID as the account to search for.  Maybe the "guys" you were talking to were referring to a 3rd party application that essentially lo-jacks your device.  But even then, it would still require Power and a network. 
I don't believe that there is currently a way to flag a specific serial number for location.
Best of Luck.
