Rhino and Brunner Pedals would work as standalone devices, DCS doesn't support trimming pedals yet natively, so you'd have to rely on brunner software for pedal trimming.
Got a reply from Virpil: ".... Considering current production capacity and your order's queue position, we estimate that your order will be fully allocated between end of January to early February" So it looks like I'll get it soon enough and there's probably no need to rush this
