I'd consider a different location...or at least a different angle etc. If the sun is at their back, you will have a heck of a time keeping the exposure of the sky under control...that is especially true if you are going to be limited by your maximum flash sync speed, which is probably 1/200 or 1/250. That will mean that you'll end up using a smaller aperture (which you may need anyway, to get everyone in focus). The result of having to use a smaller aperture, is that you will put a lot of demand on your speedlights...maybe too much and they won't be enough...especially if you want to use umbrellas and/or have them at a distance that will evenly light a large group.
A better option, IMO would be to get up higher so that the sun/sky isn't in the background at all. Then you don't have to worry about controlling it's exposure so much. Ideally, I'd suggest a shady spot that also allows you to get higher above them but it's certainly a good idea if you can bring a ladder of some type.
With a large group, you'll likely have to have the lights farther away, which means less light gets onto (reflected off of) them. This may mean that you won't be able to use the flashes for your main light source, but a bare flash can give you some nice fill and put catch lights into their eyes.
If/when you break into smaller groups, you can get the flash closer and that gives you more ability to use it as a key light and alter the exposure of the background in comparison to your subjects.
would it help if he used a ND filter to stop some light? to be able to use a slightly larger aperature?
