As stated in the comment, it's not possible.

Categories are simply tags placed on a test that allow you to select tests for execution. Once execution begins, it follows the hierarchy that you built into your tests when you designed them.

In other words, you should organize your tests into test fixture classes primarily on the basis of the setup that each test needs. If any test in a fixture does not need the SetUp or OneTimeSetUp of that fixture, then it doesn't belong in that fixture. This, BTW, is not simply a matter of opinion, it's how NUnit is designed. If your test design doesn't mesh with NUnit's design, then your tests will do it's bets to run them but you won't get full benefit from it.

Those test classes (fixtures) should also be organized in namespaces according to the needs you have for OneTimeSetUp. You can only share OneTimeSetUp across classes if they are in the same namespace.

Hope this answer helps, even though it's "No!"
