I understand what you're trying to setup HealZ, but i think it could still give someone a decent boost/and still be abused as 'donating' if open to challenge any league. Eg, bet 50 points, gain another 25 bonus for streamed, that person is quickly at 125. A while currently it's not enough to make top 32, with increased tournament activity and results they could potentially catch up quicker.
While OSC does offer incentives (particularly to SEA players) for casuals/'noobs' (To use your language), at our core we are trying to put together a highly competitive ranking system for the highest level of competition. Everyone can potentially acquire points which is cool in itself.
So i think we'll still have to stick with the established rules of close league proximity/results based allowance.
There are surely a few GPD level players with points who might be up for a challenge
