I don`t know if is clear what I want to do also I own both cars,
Thanks everybody for all the replies, hope that my question is more clear now.

You were clear enough for me to comprehend when you said,

They both tip

...yet I am not smart enough to give you a 100% certain answer.

Can they be swapped? Yes. 99.996% sure of that. It's in the details that I get a bit guessey.
You have all of both, so it should just be a matter of figuring out what parts must be swapped or kept. My catalog shows the transmission through 2003, so there's a chance they completely changed it for 2004 and I am clueless. Otherwise: The 2.7L version of the tip is ZF part number: 1060 030 050 The 3.2L version is: 1060 030 030.
A smart person could examine this: https://www.zf.com/global/media/zf_media/document/int_print_catalogs_documents/usa_4/5hp19flporsche.pdf and figure out the differences.
I expect that the Axle flanges from the S model will need to be swapped into the base model. The TCU may need to be swapped to get the right shift points and possibly prevent some sensor errors (just a guess). Other than that I expect that most of the differences will be internal to the transmission, mostly the differential, and not critical. Externally they are pretty much the same - should mount right up without issue.

My advice: First, verify the model of transmission you have. Download the linked PDF catalog and look for any key differences between the two and swap what you need between the two.
