Suggestion: The Macerator can turn gravel into (2?) flint.

You need an awfull lot of flint with industrial craft for ITNT and industrial diamonds and that kind of stuff
But it takes a lot of time to place gravel, mine it away, place gravel, mine it away and so on....
So it would be very usefull if the macerator could turn gravel instantly into one or maybe even two flint.
