Yes no problem, there's a wide range of boilers available.
Alot of new installations still use 10mm pipework. I'd imagine your's will probably be 8mm pipework.
To use the existing pipework you will need to flush the system a few times (not powerflush, unless you have problems with the radiators or sludge), ideally renew all radiator valves, and check - if not replace the manifolds, as this is where the leaks are likely to occur when changed to a pressurised system.
