Creating new hatch pattern by adjusting original

I have a wide-board floor pattern that I want to alter. When I use the following sequence:

0, 0,.4, 0,2

90, 0,.4, 4,4, 2,-14

90, 8,2.4, 4,4, 2,-14

The boards are 16 units long, with a random stagger that repeats every few rows. 

I want to reduce just the width of the boards from 16 to 10 units, and also adjust the stagger proportionally (so the horizontal dimensions would all be 62.5% of what they were before.)

The width of the boards - 2 units - would remain the same. 

I could use SUPERHATCH, but in the long run it's better to create hatch patterns that can fit the flooring / wall patterns specified.
