Yes, you can use the serials from the MBP.
The crucial values, ROM & MLB, must be genuine and from the same Mac (I also use the same 12 Digit System Serial from my mac mini but I'm being careful). The SmUUID for the hack can be unique and different from the Mac's.
Applying MLB & ROM to the "RT Variables" section in Clover (and MLB in Main Board Serial key in SMBIOS section of config.plist) ----> your hack will show the same model in the "About this Mac" screen as the "donor" Mac but since everything else in the SMBIOS section is correct, then Clover uses the appropriate SMBIOS for power management, sleep etc.
PS Why don't you create a Clover boot USB and boot into your Mavericks/chameleon install? Just find the system-ID, ROM & MLB of the chameleon install like I explained in my procedure and use them in the appropriate sections of Clover's config.plist on your USB. Run the iMessage-debug tool to confirm that all the variables are the same when booting with Clover .Go to the full post
