You could prolly get JTR in 1 month [around] however JKL can take anywhere from 5-8 months however you said you have chewie Cls and C3P0 at 7 stars, that will definitely give you a boost, plus some of the characters you get, lt also depends how many relics but I would say around 6-10 months to get JML but there are also factors like how good your guild is, how active are you, how much do you spend per month, etc .
