Hi there fellow Pentaxians,
I decided to create a new thread and ask for advice since my experience with flashes and lighting is quite limited. Here's the problem. This Saturday I am supposed to have a photo shooting with two models, they want to pose together and they sent me some pictures for inspiration so I can have an idea about the lighting setup needed. Few examples from what they sent me below. Those are not my pictures but I don't have any copyright information regarding the authors otherwise I would have posted it. In addition to those, we have several other concepts involving full body shots for both models together.
Here is a picture of the location. It's quite a large hall and we plan to combine natural light with artificial light.
I will be using the K-1 with the following lenses: FA 77mm, FA 43mm, DFA 24-70mm, Helios 58mm f2 and maybe Sigma 35mm Art. Regarding the lighting, I have several options and this is where I need you advice:
Option 1)
Use the Yongnuo YN560-III flash (which I already have) with a trigger (which I also have) and just buy a large shoot-through umbrella. I was thinking of this particular one:
Photix Premio 120cm (47")
I can also buy a softbox-like umbrella (80cm) or a bigger shoot-through umbrella (180cm), or reflective umbrellas.
This way I will have only one light source available to complement natural light from the windows.
Option 2)
Rent a lighting system. The only option that I have available locally is this one:
It consists of 2 x Elinchrom D-Lite RX4 400W with 66x66cm softboxes. This way I would have 2 lighting sources, but I'm not sure if the softboxes are big enough. This is the cheapest option. Maybe I can go for this and buy (not rent) a larger octobox or something to use it with one the flashes.
Option 3)
Postpone the shooting session and buy the Godox AD400 Pro, the Godox Xpro-P flash trigger and a large softbox. This is more of a long-term solution, I am planning to get the AD400 Pro and the Xpro-P trigger anyway, but they are not available in stock until Saturday.
What would you do for best results? Thanks a lot in advance.

Basically my concerns are:
If I go for option 1, will the YN-560III be powerful enough to light a large diffuser?
If I go for option 2, are the diffusers big enough for full body shots?
