hashcat with scrypt(scrypt)

Hello,

I am an idiot and lost the password for my Toast Ripple XRP wallet. 

I have the JSON backup. 

It looks like the Toast wallet follows the format (https://toastwallet.com/cryptodiagram.html)

scrypt(scrypt(password, salt 1), salt 2) = hash

I have hash, salt 1, and salt 2. Is there a way I can use an existing mode with hashcat to run this type of search?


Side question if you feel like answering: the number of passwords I need to check is 2.4 x 10ˆ13. Would I be able to complete such a search in a reasonable amount of time? 

Thank you for your help.
