Quick Question (Yes I searched)

Hey all, I am new to posting here. I have what I hope will be a quick question to answer: I have legit copies of The Sims 3 and the EPs and a few stuff packs. However, since I buy those legit-ly (exercising "poetic" diction with that word), I refuse to buy store content ( )- any of it. So, what I'm wondering is, will it be okay to just download and use the store content as .package files (I download my store content here: KAT: Complete Sims 3 Store Content) and use your "Store Fixes" files? Or are your "Fixes" specific to the store files you upload. The ones I download from rachelstoolbox come decrapified and merged, which is why I prefer those, rather than going year by year, month by month.

Thanks in advance for any help!
