Nah.
The Reapers started off being highly mysterious ancient eldritch abominations that over the course of the series were ruined by revealing a seriously stupid motive for their shenanigans.
The Pyramids are just as mysterious as ever and have maintained that air of malevolence they always had. If anything any lore about their machinations just raises more questions.
The Pyramids and the Traveler as far as I know are playing a game called The Flower Game.

The Reapers are not the creator of the universe know in Mass Effect. The Pyramids (
It seems to be) are the Darkness itself. The Warmind Rasputin called IT not they. So if the Pyramids "IT is" the Darkness, it is the creator of the universe with the Traveller, so far more powerful then a Reaper fleet.
Proprably one Pyramids com shutdown all near Reaper fleet, as the Darkness did to the Rasputin.
