I doubt you will be able to get the same lumen output from 5mm LEDs no matter how many you try to stuff in there.
The brightest LEDs I have seen so far are the Seoul Z-Power LED P7 (SSC-P7-C-SXO) with an output of 900 lumens (at full amperage). The light generated by these is freakish. I have two torches that use these. But these puppies get HOT and you would have to custom make both the driver circuit and the heat sink (if not liquid cool) for them.

With a custom aluminum base with 6 to 9 of these together would generate some serious lumen output.

Low-end projectors bulbs start at 1000 lumens or brighter.
The brightest LED setups are at about 1000 lumens -- but these are multiple LEDs in a single capsule or multiple capsules on a circuit board, all quite a bit larger than 5 mm.
These are high-power LEDs. A different category than 5 mm LEDs. The 5 mm LEDs don't even come close.
The LEDs will run hot enough to still require active cooling, and you might also need optics.
The type of white light emitted from the highest-powered white LEDs is "cold" white light - too blue to be usable.

This is a LED lamp that I built using Cree XR-E LEDs. There are (5) five LEDs here running at 700 milliamps from a LuxDrive at 19 volts input.
Keep in mind that these are NOT focused. With proper focus, this would produce about 1000 lumens. Push the amperage up to 1 amp and your looking at 1200 lumens.
Swap these with SSC P7s and your looking at 2900 lumens at 700 milliamps. Push it up to 1 amp and your looking at 4500 lumens. It's doable with the proper heat sink. Any machine shop could make one from a block of aluminum for a couple hundred bucks.
The temp of the light definitely would make a difference. If you could find a bin where the temp is around 4500K, that would work well.

whatz up everybody?
I'm very new to this, so go ahead and get your noob jokes out. but wanted to say thanks for you help. I'm the friend that Sulla is helping out. i have a new question you you guys. I have a TOP OSRAM dlp lamp that I'm wanting to use to make a DIY projector, only thing is i don't have a driver for it. would you guys have any ideal how i can fire it up?
TOP OSRAM P-VIP 100-120/1.0
thanks

I responded in email to this question but I will post it here for educational value.
The DLP lamps are just like a florescent bulb or HID bulb. They require a driver/ballast to fire.
These can be found online and http://www.discount-merchant.com sells a number of different ballasts ranging from $50-$175.
