No hanger and only 4 ASMs doesn't make sense to me, and excuses why, whether for comfort or cost makes even less sense. Basis already exists to make such.
Export P18 corvette, based on Type 056, has both a hanger and with enough space for 8 missiles.
Thailand's Chinese made Pattani class OPVs are said to be the Type 056's evolutionary predecessor. While the OPVs don't have missiles, the basic hull design appears to have space for them as a provision, enough I think for 8 missiles in two quad packs. There is the hanger.
Chinese made Nigerian P18N corvettes or OPV. These don't have missiles or sonars. Note the hanger and once again, the space between the superstructure and funnel.
