moving the throttle will be pretty straight forward, cables (length) will be the toughest part. your clutch being on the same bar will be tough at first, think of rolling on the throttle while also easing out the clutch on the same hand. My 65 lambretta has the shifter on the left grip (like the throttle you twist it) and a normal clutch. It can take a bit to get used to the left hand doing more complex motions than it has been trained for.
To keep riding you do what you need to do. I had a guy bring a gold wing with sidecar into the shop once, he had just bought the bike and wanted us to, well.... make it closer to stock.
The previous owner had been missing a limb or two and another shop had modified it a bit.
The clutch was on the right
The brakes were all linked to the left lever (even the side car wheel)
The shifter was the goldwing reverse lever used like a suicide shift
New owner though he would be missing a few parts soon if he didn't change some things back.
