That would be great.
Grbl 0.9j has better trajectory planning and smoother stepping which allows faster scanning. If you build the hex file and post it that would allow others to simply upload it using XLoader, so they don't need to compile it.
Here are my settings for 0.8 and 0.9...
Grbl 0.8
$0=80.000 (x, step/mm)
$1=80.000 (y, step/mm)
$2=80.000 (z, step/mm)
$3=10 (step pulse, usec)
$4=1000.000 (default feed, mm/min)
$5=500.000 (default seek, mm/min)
$6=0 (step port invert mask, int:00000000)
$7=25 (step idle delay, msec)
$8=60.000 (acceleration, mm/sec^2)
$9=0.050 (junction deviation, mm)
$10=0.100 (arc, mm/segment)
$11=25 (n-arc correction, int)
$12=3 (n-decimals, int)
$13=0 (report inches, bool)

$21=100 (homing debounce, msec)
$22=1.000 (homing pull-off, mm)
Grbl 0.9j
$0=10 (step pulse, usec)
