Processor upgrade Intel to AMD

I am planning on upgrading my system board and processer. I will be replacing an a p4 with an athlon 64. I have a ton of stuff installed and configured just the way I like and really do not want to rebuild a system from scratch. Is it possible to configure and save a new kernel with the info for the amd motherboard and processor built into it, power down, replace the hardware and boot into the new kernel? Can I then change the cflags and re-emerge system && emerge world? Will this approach work? If so what flags should I use with the emerges?

Thanks

I've built packages which were not available for AMD64 using the x86 flag and they worked fine (as they should, since the Athlon64 is backwards-compatible with 32-bit x86 code), so I expect your idea will work.

The flags I use on my Athlon64 machines are:
CHOST="x86_64-pc-linux-gnu"
CFLAGS="-O2 -march=athlon64 -pipe"
CXXFLAGS="${CLFAGS}"
