I don't have a plan at this moment.  If I am to move away from cc0, I
would probably need help from other people.  As Alex has already
pointed out, my main concern is whether code quality stays the same.
If every insn carries a clobber of the cc reg, some optimization
passes may not like that.  Elimination of redundant test instructions
is part of code quality.
