    Setting up the joins between tables or creating consolidate derived table in universe is the same thing as derived table doesn't hold the the run time both way joins are going to come in the picture.

    i would suggest to look at the requirement and design the universe with combination of joins between tables, use short cut joins ( if possible so that extra joins can eliminate).Read purpose of the derived table and when to use.

    Derived table will not solve the problem in your case.
