Help us light our green screen studio

We are opening a small green screen studio for videography on a supple budget, with a limited yet growing knowledge that we hope you can help to expand.

We are exploring our options for having the most appropriately diverse lighting choices possible within a limited arsenal.

With that being said, we have selected fluorescents (with electronic ballasts to prevent strobing, of course) in general to deal with lighting our models and subjects under the traditional 3-point system, as well as our chroma walls and floors separately, in an even, diffuse manner.

To be specific, we have selected 8 (one spare) in total of a dimmable (2% - 100%) light made by Cool Lights: the CL-455MD model, which is a 2', 4-lamp, 55watt-per-lamp fluorescent bank, that produces the equivalent of 900 watts in brightness, or nominally at 2900 equivalent lumens.

Without getting technical, the dimensions of the studio space are roughly 12'x12'. The ceiling tiles are also chroma and can be removed to add above-deck fixtures in the future.

But for now, the idea is to dim down as needed to fit the roles of the 3 point lighting system, and then also a little lower in illuminating the screen (one bank from outside of frame left / same for frame right) and the floor (same setup as wall) separately from the subject.

Currently, we plan to use softboxes to diffuse the light, gels to adjust the color temperature whenever necessary, and flag kits and black foil for controlling and shaping.

I suppose our questions are, how does this sound as a viable setup? Are there alternatives that are more reasonable in terms of cost or practicality? And also, using a couple of flag kits or something else, how effectively & diversely would we be able to shape and otherwise control the lights upon our subject if we stuck pretty close to the three point system? And finally, is there any part of the picture we may be missing? We are aware of issues such as green spill and motion blur.

Thank you so much for your input, and for reading my lengthy post.
