I do not understand what you are asking for. If it is that you get a random Gold Rune every time you buy a Sinergia, then I am against it. The the cost of synergia does not warrant a Gold Rune.
As far as I can see the purpose of Sinergia is so that you do not have to so all the manual clicking to get the runes used to upgrade other runes and nothing else. That is what you are buying is the chip experience and nothing more. It is not meant to be a replacement for the Rune Temple. If it were it would make the 'Combine lower level Runes' that some players got by upgrading their VIP level meaningless.
One thing that I think that can be done to make the Rune temple less of a chore is to get rid of the 'Sell all' button and have it done automatically when the 'Rune Chest Full' message goes away. This will reduce the number of clicks needed by a significant amount and it does not affect the 'Combine lower level Runes' since you still have to do the Sell All if you are using it.
This is my opinion as a player anyway.
