Good luck with the ECU swap. I started looking at this possibilty for a different reason. The Crossfire sends the start signal from the key into a dedicated pin in the ECU while no V8 with ME 2.8 ever did this. All V8's get the start signal through the CAN. When Rudy did his first 55 Kompressor swap, he discovered a reminent file that allowed him to start from the key. Rudy did a lot of checking and found that file is only in the 55K ECU. As 32Crazy said, Every time I start my car it looks like I am stealing it.

I am betting that if you swap the ECU, you will be able to sell the AEM. But swapping the ECU does open up some new bag or worms but I believe they will be much easier to deal with than the AEM really big bag of worms.

As you know I also intend to boost my engine as well, but starting from the key is very important to me. I had spoken to Jerry at Eurocharged and he thought that using the 55K ECU with a turbo sounded very doable, especially since it had already been done when an SRT (Importlab) went from S/C to Turbo. Jerry thought the 55K ECU would get me in the ball park and he could fine tune from there.
