Seriously, I am not the "maintainer" of GCC diagnostics or even Wconversion.
Anyone can contribute!

Yes, it may be possible to provide such an option. I am not against such an
option and even if I were I cannot stop you from implementing it and getting it
approved by GCC maintainers. I don't know how much work it would be to
implement it, and out of kindness I might invest some of my free time to try to
do it for GCC 4.6. But even if I might try, that won't happen before summer
almost for sure, and then GCC 4.6 won't be available before late next year.
