There is no problem with you doing that.  The pump will recirculate any unused fuel thru the return line.  
The Injectors will be handled thru the AFC.  Generally, you need to get on a dyno to tune the AFC, but you should be able to tune the injectors down 37% to run the same 280cc of fuel as the stock injectors provide.  Also, the pressure regulator (RRFPR) wont increase the fuel pressure without boost, so that would be fine too.
