Will a larger tankless coil fit in my boiler?

A bigger coil will not produce any more with out higher btu input..140000 btu input will produce 2 gallons per min..Give and take .If you want 5 gallons per min you better be firing 350000 btu input. and that's with out putting out to heat your home..A bigger coil will be useless.

You need a storage tank or hot water heater.
