Left handed to Right handed question!

Yes, it's possible. How much money do you want to spend? The cheap way would to be replace the nut; string it right handed; and play it "upside down". But, the controls might get in your way, and, that bridge isn't easily convertible. As it is, I'd bet money you'd never get it to intonate. You'd need a right-handed one, which is not too hard to come by. But, if you do convert it, let me know. A left handed Hofner bridge is hard to come by - very hard - and I'd put it to good use.
If you wanted to spend the money and do it the "right" way, you could yank the whole top off; patch the existing hole for the controls; and cut a new one. And (maybe successfully) cover up the surgical scars... And, do the whole bridge/nut thing..
The pick guard? Yes, a right handed one would fit on it fine. Just need to drill a hole or two.
But, to he honest (and speaking as a lefty), it would be nice if you just left it alone, and sold it to a lefty who'd really like to have one. Lefty anythings aren't real available, and it would be a shame to make one of them disappear, when you can buy a righty almost anywhere...

 

The easiest way is to convert the left handed into cash, and convert the cash into right handed.

 

Find a lefty player and do some horse trading.
