You don't have to use /usr/src/linux, the system would need its own kernel 
tree at different location (installed by the distribution or copied by a make 
target similar to modules_install when you compile the kernel yourself). You 
shouldn't even access it yourself.

For each kernel release there must be a gcc version defined, and the 
compilation system must have this gcc available. This could mean that you 
have 10 gccs (if you have 10 different kernels installed). These gcc's should 
not be in the usual PATH directories (/usr/bin..) but in a private directory.

IMHO it is neccessary that stable kernels keep source compatibility.

But it shouldn't be a problem to su to a special user for compiling.
