New Commodore-Amiga machines might still be possible.

Neither Amiga, Inc. (with respect to Amiga-related products) nor Commodore create new products. They both simply repackage products created by other companies. So, best case, you'd get an Intel PC with a silly C=/boing ball logo capable of running Amiga Anywhere.

ya know...Amiga only lacks power to crunch all the numbers that today's environment demands.  Why couldn't Amiga be a stand alone OS, get aweb and ibrowse using the newly available ram and clock speeds of a peecee and other programs that exist could really use a face lift but fundementally most are pretty solid programs. Amikit/amithlon done right could really be a viable alt. OS.

new Commodore could sell again Amiga with AmigaOS if OS4 is ported on x86

Well, if you might have an idea for a 'new' platform. Why not start your own company developing them. Ignore all fellows saying your stupid, that was told to Jay Miner is those days too.
Custom chips is the way to go, when you want to do something different form the main crap. Without those custom chips, it will just be 'another' PPC(?) platform like all others.
Capable of doing just the same like the other, you need a new, fresh, innovating ideas.

You will also need to rewrite kickstart, but that had to be done anyway. Kickstart is unix based, so start from there with Amiga in mind.

The name 'Amiga' is just a name, maybe possible to buy the Amiga Inc. is dead..

I though many times of doing something like this, but haven't had the guts to do so...

Oh, and don't let anyone scare you by saying custom chips is very expensive. They are not, there are a lot of asic specialized company's, that can make you custom chip for a few thousand dollars. The reason company's like Sony and Microsoft spent so much money is because of the overpaid employees, which think they are so important.
