I can hardly see the tablets you mentioned "real gamechanger" and reasonably profitable.
Please also keep in mind gp/hr is a balance issue. I seriously doubt Jagex wants more gp flowing into the economy per hour anyway. Besides, if they want more gp/hr, they can just shorten the duration of cooldown of the spell.
We have all kinds of Enchant tablets in the game for a long time already, but look how they become garbage. They are hardly game changers or profitable (big money loser indeed) because they are rarely used. Think in this direction... how often do you need Contact NPC? Do you really save time making or buying such tablet from the GE, searching them and taking them out from your bank before you use them? No. you don't. You are just wasting more time and more bankspace.
