Simplest solution? Wear the lowest ilevel gear and beat the raid with it. That's basically what you're asking here.
If you still think it's easy then SE can lower the ilevel more. There's nothing wrong with wanting a harder content.
What's wrong is you're not doing it harder but want to block other players from completing their goals.
If your goal is to have harder content then do it the professional way, don't be an amateur.
