LEED for office with few modifications

A project I assess is seeking LEED v4 CI Silver. It is a 5877,1sqft rented office, in an existing building (previously certified Breeam in-use), that is undergoing fit-out (minor improvements = paint, lighting replacement, a toilet will be suppressed, new furnishing and a small cafeteria will be created). There is no modification on the heating and cooling equipment, so no new control systems or a more efficient equipment will be installed. Also materials where not chosen according to LEED requirements. The project team contacted us during the construction phase to pursue LEED certification on a silver level and the scope of works end in a month. Therefore, do you think it could be possible to obtain the certification at this stage? Thanks in advance.
