Hmm, well, I've done something similar to this and it worked, but for a whole dining table I'm not sure.
Basically, clean the whole table well.
Then lightly sand the whole thing with very fine (400, maybe even 800 grit paper). Vacuum, then wipe it down with cheese cloth to remove all dust.
Then reapply a lacquer coat to the whole top. I'd just be concerned you get a "pit" where the acetone had spilled, but a light sanding to smooth that out should take care of it. Doing that, you shouldn't have to restain anything. You may have to repeat the process several times.
I +know+ that it's generally safe to sand lacquer (or just about any clear top coat) and apply another coat on top. That's how you'll typically build up a clear coat. My buffet top has 8 coats of wipeon poly, each one sanded lightly except the last.
Just make sure you're using the same type of finish. (Lacquer on lacquer, poly on poly, etc). Otherwise, you'll have a huge mess.
If you can test somewhere underneath or something would be best....
