Alkyd will fade over time. Some colors and paints less than others. I have no know experience with Van Sickle paints but Alkyd will fade. Months to years depending on the UV light exposure. Some Alkyd paints are acrylic modified and have better UV protection but will still eventially fade. What to do depends on you, not everyone wants a $300-$400 a gallon paint. you determine the level you want.
I have not had any cross reactivity between an alkyd topcoat and a lacquer primer.
