1. Make Fi inherit from Fi+1.
2. Use something like this:

template<typename T1,typename T2>
struct FixtureCollector : T1, T2 {};

You can now either implement above using variardic templates or implement macro
that will convert PP sequence into sequence of FixtureCollector<T1,...>:

For example 

FIXTURES((T1)(T2)(T3)) should generate:

FixtureCollector<T1,FixtureCollector<T2,T3> >

use it :

BOOST_FIXTURE_TEST_CASE( test_case1 , FIXTURES((T1)(T2)(T3)) )
{
}
