Need advice: should I open the back of a 2013 Retina MacBook Pro as a means to recover data?

A Late-2013 13-inch MacBook Pro Retina (MBPr) of mine was fried by a water spill and some very important data is on the SSD. My most recent back up doesn't include this data. I know the computer is fried but I'm not sure if the drive is recoverable or not. Sparing the details, recovery of this data is very time sensitive. Attempted solutions thus far: 1. I took off the back of my computer to check if the drive was recoverable. Unfortunately I need a SSD adapter for an A1502 MBPr drive to find out, so this is not an immediate solution. I looked into purchasing a connector but everyone I found online won't arrive for at least a couple weeks. I can't wait that long. 2. The company Apple recommends you take your computer to for data recovery wants ~$1000 as an estimate, and the turnaround time is not guaranteed. This is the "standard priority" price, meaning I might spend money that I don't have and not even get the data recovered in time. My thoughts on my next attempt at a solution: I've ordered a new MBPr to replace my old one. It arrives in a couple days. My thought is to take off the back of my new MBP and plug in my old drive. From what I've read Apple hasn't updated their SSD drives since 2013, so my old drive should be compatible with the new MBPr. If the old drive is okay then I should be able to restore my data before the weekend. I'm asking for opinions on this solution. I recognize that this would void my warranty, but it is also my understanding from a friend's friend that works at the Genius Bar that there's no way for Apple to ever know I did this should I need to use my warranty for something in the future. For what it's worth, I would do this with the assistance of a very computer-savvy friend. In particular, I am wondering if anyone can answer the following: 1. Can anyone confirm that my 2013 A1502 MBPr drive is compatible with the current MBPr model? 2. Will opening up my computer and temporarily swapping the hard drives compromise my new MBPr in **any** way? 3. Am I misinformed about Apple being unable to know I opened the back of my new MBPr should something go wrong? Alternative solutions welcome. Please help.
