Why would you want to get rid of the 2m hex grid? That is a terrible idea. Speaking as someone who has published several products, the 2m hex grid is a producer of sanity and reasonableness. It keeps older players who use previous editions grounded and things convertible between editions with minimal effort. The 1m scale makes all combats take place in areas the size of a shoebox.
Removing the grid has the additional ridiculous out of game effect of making mapless combats for low-income gamers, which is really mean-spirited. The size of a combat is often based on the size of a table. Lower income gamers have less space for the table, and a smaller table. My game table, which is basically a large thing my friend made, cost about 1400 dollars. Most people don't have that kind of money to burn for a 10 foot by 4 foot table that seats 10 people comfortably or about 6-7 gamers with their books, equipment, and their raw physical size.
There are a million reasons to keep the grid, and almost none to getting rid of it, unless you're going to change the cost of every movement power in the game.
