Just a little late, but hopefully this will pop up for others who are trying to figure out how to do the same thing (like me!)
Here's what worked for me (YMMV):
Open up your CUI (Customize User Interface) by selecting 'Tools ->Customize->Interface...'
Create two new macro buttons, one for "Plot Previous Style" and one for "Preview Previous Style".
(The second toolbar button isn't strictly needed, unless you want to quick-check that your 'previous plot' settings are really going to work on the current layout.)
Note1: I just duplicated the existing 'Plot' and 'Plot Preview' buttons, then renamed them and edited the graphics a little so I could tell them apart on the toolbar. Save button graphics to new files!
Note2: After you are done editing your buttons and macros, remember to 'drag' them from the CUI interface to the toolbar location you want to put them, so you can use them!
Enter this macro string for your new "Plot Previous Style" button (al lthe same, no extra spaces, etc.):
This macro basically enters the command line sequence to plot the current layout using previous plot settings, and saves the plot settings to the current layout. If you want to do the same thing but don't want to save your 'previous plot' settings to the layout, use this instead:
Enter this string for your new "Preview Previous Style" button (optional, as mentioned above, but I have been finding it handy):
As you can see, it looks very similar to the 'Plot Previous Style' macro string, however this time we're 'pretending' to plot in order to apply and save the 'previous plot' settings to the layout, then calling the 'preview' command from the command line. Unfortunately, this time you really do have to save the plot settings to the current layout, because if you don't, the follow up 'preview' command will just use whatever plot settings are saved with the file, not your 'previous plot' settings.
Hope this is of some use to others who are as frustrated by AutoCAD's archaic plot gymnastics as I was!

even though your examples were for lisp (not supported by ACad LT, as far as I can tell), they gave me the hints I needed to figure out the macros.
Sorry, missed an acknowledgment:
Posts by Eddie and keepviper13 on the autocadeverything forum were also quite useful in figuring out how to do this:
