I think one way to make a "Sugar lump" building interesting would be to give it a drawback: Each building reduces the sugar lump timer by 30 seconds, but give a -1% cps multiplier. Upgrades can increase the reduction time up to 1.5 minutes and the multiplier to -0.1%. (450 fully upgraded Elder Gods reduce 11.25 hours but have a -45% effect) It should probably cost more than the Chancemaker or something. It could also be interesting to unlock it with a heavenly upgrade maybe?
The Elder God itself could look like a crystalized Lovecraftian horror with a description along the lines of: "Sacrifice cookies to sweeten the deal!"
