I know you are specifically asking Amal and No real point answering you since you will wait for Amals reply anyway
, however I may be able to help a little… 
since I have sent him 2 cards for conversion.
For what it's worth
- One of mine was also a DESFire EV1 transport card
- The dimensions appear to be the same
- If it has “wings” it will make attaching the antenna viable, it is hard to discern them in your image but it looks like it to me
- NXPs TagInfo will return 17pF capacitance which is suitable for Amals antennas
So in my opinion YES looks viable.
Send it to him as is, not like this idiot who sent him the exposed chip
Did your transport authorities get back to you or are you just getting your ducks lined up ?
