Lay out and light expanding help

Hey guys, help me out if you can. Attached is the layout of my room now. I started this thing just playing around, but it has become an addiction since. I built this closet in my toll shed thinking it was perfect. I have since discovered that cloning is as easy as oversleeping and I want to expand in this 10x10x7 space.

I want to add (2) HPS light 600 or 1000?

I currently have a 400w metal halide not in use and a 1000 mh in use

I want to clone under cfls (2 weeks?)
Pre-veg under 400 mh (2 weeks?)
Veg under 1000 mh (4 weeks?)
Flower under (2) hps (8-10 weeks?)


The thing is I want to be able to be in the veg room when lights are off in flower. As it stands my closet would be perfect for veg and main room for flower.

(1) How should I lay my room out without cutting walls down?

(2) What size flower lights should I use to keep an even rotation with my metal halides?

(3) I would like to set it up so that every 2 weeks I am moving clones to preveg and so forth.

Sorry for the long questions guys. What do you think?

On second thought, as far as layout i guess i will add a 3x4 area and have an L shaped flower closet with (3) 1000s this will give me 83 watts a sf. this way i can do a four week rotation 4 under 400mh 4 under 1000mh and a total of twelve weeks flower. Am i wrong by saying this should put out about 2 lbs of dry bud a month?
- This will make it to where i can enter the veg room with flower attached.
