Neat question. I’m a ham (amateur radio) and moon bounce is fairly common. Doing a bit of research I found one mention of people doing successful sun bounce but I haven’t found any details:

So it looks like it’s possible but not practical or common.

Amplifying? No not at all. These bounced signals are very weak on the way back.

thanks.. I also got an ham license, not sure if it's still valid though because I haven't needed it in many years.

I'm not a radio (or I guess radar) guy, but a terawatt sounds like quite a lot of power, even if you are pulsing it.
