On JtR 1.7.4+, you can do this with:

[List.Rules:Wordlist]
=[1-9A-F]  ^  X\p[2-9A-G]z0 'l

or with:

=[1-9A-F]  x\p[2-9A-G]z $  X0\1z

but these are inefficient.

Maybe I should add a "search for character and assign position to
numeric variable" command.  I just wrote this thought down for further
consideration.

Thanks,
