Can two .pac files be combined?

[MrPotatoKyle]

I'm trying to get a stage expansion pack (Melee and 64 v2) and I want to have all these files included without losing previous files (such as common5.pac, sc_selchar_en.pac, info.pac) Could I possibly merge these, or combine them into one. A detailed method/program would be appreciated

No.
