Probably not, because cracking speed is usually CPU-bound (not I/O bound). Doing runtime decompression would increase CPU usage rather than reduce it. Wordlist files aren't typically larger than tens of megabytes. For comparison, modern 7200RPM hard disks can easily do over 50 MB/s for sequential reads. However if there really is a good reason, you could pull this off using widely available compression tools like gzip/bzip2/lzma by piping their output to john's stdin. They would probably also have much better compression ratios (>5 times is normal for text files).
