"Every NG unit could do its two week annual training on the southern border."
Yeah, sure. If every NG unit did its training on the border, at the same time, you'd have enough manpower on hand for two weeks.
The problem is that there are FIFTY-two weeks in a year. And chaining every national guard unit in the country to the Mexican border means that we will be unable to fight a war anywhere else.

52 weeks in a year means 26 annual training periods. I'm fairly certain that there are at least 26 brigade sized elements in the National Guard. A brigade can cover a lot of frontage, although certainly not the whole border. Nonetheless, 132 Bradley Fighting Vehicles roaming up and down the border would certainly be a deterrent.

It isn't the National Guard's job to fight wars anywhere else. Defense of the borders of the US is one of the Guard's stated, mandated missions. The Guard has been misused for the last 25 years as the backup for the active duty.
