Default Capping off burners on steam boiler to reduce BTU output

A friend of mine has a Weil Mclain gas steam boiler that was put in
about 15 years ago. Apparantly whoever put it in oversized the job and
put in a 300,000 BTU unit, when it should have been a 200,000 BTU unit
according to a heating specialist that recently surveyed the house.
One suggestion he made is that since there are 12 venturi burners
under the boiler, is to remove 4 of them and cap the nozzles, thus
leaving only 8 burners. He said each burner outputs about 25,000
BTU's, so that should reduce the output.
My question is does this make sense? Theoretically it sounds like it
does, and from a safety standpoint, as long as the gas outlets are
capped, it does not seem unsafe.
Any thoughts?
