Alternative ways for making a point grid.

Hopefully I can explain this inquiry a little better than my title.

I'm working in Adobe Illustrator CC and I'm trying to make a point grid for a brand system.

Basically to make a point grid I would normally:

1. make a normal grid

2. make a shape

3. line shape up with top left point of grid

4. alt-drag to next point to the right

5. cmd-D to copy over along all points

6. take top row and alt-drag to row beneath it

7. cmd-D until the grid is made

8. delete background

I'm trying to make a point grid based off of the second grid in my image though which is skewed to get smaller as it goes towards one point and I can't use the method state above.

Is there a simple way to make a point grid that I'm missing? or would it have to be done by hand?

Any ideas would be super helpful! Thank you.
