Reuse of rejected passwords by optimized kernel -O - Linda - 12-14-2021

If you run -O (optimized Kernel), passwords over 31 letters will be rejected, which is very handy. Is there any savvy way/flag to re-run from command line the rejected passwords on non optimized kernel (no -O)? Like ignore/reject passwords below 31letters.

there is a rule for rejecting plains 

Reject greater
>N
Reject plains if their length is less than N
>8
* Indicates that N starts at 0. For character positions other than 0-9 use A-Z (A=10)

Thx, just testing out. Have not figured out how it works if you have 2 wordlists. Tried with -k "<R" but did not work as expected. I think it uses right file in this case. Trying with -j instead to see if left file will be used, but hashcat in this case started to reload whole table which is 4TB, so will take 4h to confirm. But if it works will be very handy as I work with huge pre-generated files. Thx
