Godox AD200 (Pro?) vs other Godox lights for background lighting?

Hey everyone !

Those last few years I've slowly started buying some Godox lights for use in a studio. I don't have much right now, but I splurged on a DP600III as a main light, I have an FV150 for when continuous light is needed or as a secondary flash, as well as a TT685 that I can use as a secondary light or when I'm shooting outside. All of that is controlled through an X pro.

My main issue is with background lighting, particularly when I want to place a light behind the subject. The TT685 doesn't have a bare bulb, so it's a bit hard to get a nice even illumination with it, even when setting the focal length to the minimum. If I want to place it behind my model I usually can't use a softbox in those situations and depending on the space I have it makes it even worse in terms of evenness.

So I was looking at alternatives. The AD200 (maybe the pro version) piqued my interest due to the dual heads. I do find it a bit expensive to relegate it as a background light, but I can also use it when I'm shooting outside as a companion/replacement to the TT685 so it's not entirely wasted. Plus I sometime lug around my DP strobe for shootings on locations, there could be situations where the AD200 would be enough so it would lighten my load immensely.

On the other hand Godox also carries medium-sized strobes, like the MS200 and at almost a quarter of the price of an AD200 pro. But they're a lot bigger, so it would be harder to place them behind a subject.

Another avenue I could go down is stick with speedlights, but get a couple of them (either another TT685, or two V860 or something like that). It would help to get an even background, but only if they're placed outside of the shot, so it doesn't help with the situation where I want a light behind my model.

So in short, my question is: what would you go for? Considering I already have a main light and a fill light, what would be your go to lights to get some nice background illumination when required, and maybe some other possibilites outside of that use case?
