Yes. We agree to you and it looks very much feasible. 

Is it possible to have the same set of values (matching the Renesas SHC
values) for "e_flags" as generic and not option dependent?

A suitable modification to sh_elf_set_mach_from_flags in elf32-sh.c 
would do what you want. It would be fairly simple to code a mapping of 
Renesas eflags to BFD mach.

However, it isn't obvious to me how one would know *when* to treat the 
flags as GNU or as Renesas. An -mrenesas option might allow the use of 
Renesas binaries, but does not provide any interoperability - it would 
misinterpret the GNU eflags.
