You can use the KnownForce (external mode), rules, prince (plus
rules), or mask mode.

Mask: (I don't know how to escape star, semi-colon, colon, gt/lt,
question mark...)
-mask=F6TgW8D8[!@...^]F6TgW8D8[+={}.,-]F6TgW8D8?s
or
./john.exe -stdout  -mask=F6TgW8D8?sF6TgW8D8?sF6TgW8D8?s  (three "?s"
will produce near 36k passwords total)

$ ./john.exe -test -format=luks
Will run 4 OpenMP threads
Benchmarking: LUKS [PBKDF2-SHA1 128/128 AVX 4x2]... (4xOMP) DONE
Raw:    39.3 c/s real, 10.0 c/s virtual

Should take 15-20 minutes... on my stupid lappy.
Again the mask could be more efficient, but with luck you can crack it
in less than an hour.
