YES (SOMETIMES)
I hav done this on many occasions,as long as u cut the ts in as low as possible in roof space and the f&e tank is roughly 1 1/2 meters above to ts u should b fine,if not u may hav to pressurise the system

NO YOU CANNOT !!!

You will have to bring up a pair of flow & Returns from the existing system bellow, You may also have to raise the height of the header tank to ensure sufficient head of water, you may even have to consider converting to a pressurised system to achieve this

You will need to fit TRV's to the radiators to comply with Building Reg Pt L1
