Definitely no togas - contemporary dress. The closest toga-seeming and almost exactly contemporary with Marziano's project is Taddeo di Bartolo's frescoes of four pagan gods in Sienna's Palazzo Pubblico (c. 1414). I've haven't found anyone else point this out, although obvious when you put them side by side, but even someone as cultivated as Alberti "stooped" to borrow from these images of the gods in Siena - the wings of his eye emblem is an exact match for Jupiter's eagle's wings (low res of Jupiter's eagle, always find to hard a good image online of that for some reason)):Ross G.

We know how he treated Jupiter and Venus in 1403 - just as contemporary people, really. But does this give us the full picture? Would Neptune just be Jupiter in a sea-chariot with a trident?
He knew togas, at least at some point. I ordered some drawings from Vienna when I first started working on this, in 2003, which shows figures dressed in togas. But would he have made classical-style gods in the teens? Or would he just have gone with the Ovid Moralized tradition?
Anything contemporary of course, including the manuscript production centers in the Low Countries and N. France. Yes on Ovide moralise, the Visconti Hours of course, but also mine the nobles in the tacuinum sanitatis - numerous bird scenes (just add the relevant god/dess attributes - at least useful for the Kings):
