No. Neither will work.
The ECU has to be mapped to the SKREEM so one from another car has to be configured for the SKREEM in your car, unless you get the SKREEM and chips for the key fobs from the donor car.

An N/A ECU does not have the code for the supercharger or the tune of the supercharged engine and I suspect it won't talk to the SRT6 TCU, either.

So it's a "NO" for all your questions, but we do have another question: What can EUrochared do for you? Perhaps (I simply do not know) they can remap the ECU for your car.
The ONLY person you should be asking is Eurocharged themselves.
