To be honest, I'm not sure, I don't RS gold really like the grind either, which Jagex is coming out with EoC to (hopefully) solve the issue. EoC is perfect for me personally. I only want EoC to be able to degrade swifts and goliaths. GF everyone who got an axe, right?
The main issue is just that, what can you do to stop the grind? A high-level game that grants you more XP but is also instanced would be the best cheap OSRS gold option. You won't get crashed to death. It's like Dungeoneering. The high-level content could either a) provide you with food/pots or b) give you enough money to buy food/pots. They just need to make sure that it's not bottable, and I think it could be a success.
