Yes, you can use CreateMetaFont to create a new meta font name. Then, you can use LGSetLegendCtrlAttribute to set the LG_ATTR_META_FONT attribute to the new meta font name. Note: There is a mistake in the function panel for LGSetLegendCtrlAttribute, it puts in LG_ATTR_FONT instead of LG_ATTR_META_FONT, so you will have to manually edit that to get it to work.
Your code will look something like this:
CreateMetaFont ("LegFont", "Arial", 16, 0, 0, 0, 0);
LGSetLegendCtrlAttribute (panelHandle, legendCtrl, LG_ATTR_META_FONT, "LegFont");
