F1 race director Charlie Whiting says the aim is to use 2021's regulations overhaul as an opportunity for a dramatic reduction in the number of penalties imposed.
F1 boss Ross Brawn has long made clear his frustration with the amount of grid penalties drivers currently receive.
"We would like to get rid of all grid penalties, if we could," Whiting said.
"That's what we're working towards."
When asked about changing gearbox rules in the short term, Whiting replied:
"If we changed to anything it would be to a pool of gearboxes, like we have a pool of engines.
"So you are only allowed three gearboxes for the year and do what you like with them, but that's all you will have.
"It is one of the things we're thinking for 2021. We are introducing a fairly comprehensive package with a number of changes."
