The L1C code is something different than L1 C/A, so it help to some degree.
Better handling of ionospheric delay than standard L1 C/A code tracking
do would do quite a bit more.
L2C and L5 would be useful. Doing the same for other GNSS too.
As for increased radiated power, we already have that. It's been a
resident capability of Block IIR, or at least later in the series, and
was turned on for a test. The impact have been somewhat better precision
but not any bad issues that I've heard of.
