yes it is possible toupgrade the system to a sealed one using a system boiler as you mentioned. the thing to bear in mind is to upgrade the radiator valves to pressure rated ones 10bar.
The probable cause of the over heating is down to the system being sludged up/cold feed blocked, or possible pump circulating problem?
I would recommend the installation of a magna clean filter to help keep the new boiler clear from system debris.I would definately power flush the system, if the system is a twin two port valve system then a automatic bypass should be fitted, all of this done by a corgi registered gas engineer

If you have to push the reset button it suggests that the boiler/water heater is over heating.What boiler is installed?

Possibly due to a power failure, control unit needs to be reset. Hit reset button. Hold for 30 seconds. Also no fire typically due to nozzle clogged, no fuel which means control will shut down. Water in fuel will also shut boiler down. Clogged filter will decrease fuel flow. Electric eye face is dirty which will also shut it down. If you have a two line system, open up bleeder and see if you get a good flow. Check electrodes for burned ends or out of gap specs.

Your boiler has an expansion vessel that is like a bladder full of air. Yours has lost it's air pressure. Check your manual for this vessel and where the valve is to re-inflate it and what pressure to inflate to. It should have a simple tyre valve, pump it back up (usually to about 1 bar after releasing the water pressure) and should be all fixed. If you can't re-inflate the bladder is holed and the expansion vessel will need replacing.
