dunno, maybe? ch32v003 is rv32e, so rv64 seems out of the question. more likely than supporting rv64 on ch32v003 and its successors would be supporting an rv32i mode on rv64 processors, which only costs a few gates. or, for write-once-runnish-anywhere, as/400-style/android-style compilation to native code at installation time, or nvidia-style compilation to native code at load time, or transmeta-style/qemu-style compilation to native code at i$-miss time
the preprocessor thing depends on what it is that bothers you about the grotesque compilers. a macro preprocessor can be pretty small; gpm (basically unix m6) was reputedly 250 machine instructions
historically 'worse is better' and 'the innovator's dilemma' suggest that adoption of an innovation like risc-v depends more on conquering the low end of the market long before the high end. but then there's the tesla roadster...
