5% on $135B of imports raises $8B in direct revenue annually. Not enough. IT would take may years.
Hopefully Mexico will have caved by then.
BTW, I’m seeing a figure of about 270-290 Billion a year. That’s based on the following article which makes reference to 2016. I haven’t found more current figures.

If that figure is accurate, we’d be taking in about 1 Billion a month at 5%, 2 Billion a month at 10%, etc.
