Boost.Test do not support this setup out of the box

Which particular part?

This is not a good idea. You are changing test tree on a fly. Your best shot
probably is to try ot do this in global fixture. You do not necessarily have to
use the macro. class test_suite has add method that expects test_unit_generator
const&. You can implement your own generator. Also you probably should register
your test units directly under framework::master_test_suite()
