However, I recently acquired an Lbb with no monetary loss of my own ( Thanks BlackFox ), and finally decided what to do with said blaster. So, with out further ado:
Pinky and the Brain
Supplies Needed:
HOTGLUE
Amazing Plumbers Goop
E tape
1/2 in. SCH 40 PVC
9/16ths brass
19/32nds Brass
3 1/2 in. Sch40 Pvc Couplings
Ace#49 spring
Tools Needed:
DREMEL
Hotglue Gun
Band saw
Screw drivers
This writeup will come in two parts. First, the NF mods, then the LBB Mods.
Act 1: Pinky
First take your NF, open it up and remove all the useless AR drivel. Then take the plunger rod out, etape and lube the plunger head, and then swap out the wimpy stock spring for the Ace #49 one. I had some spring shenanigans after this picture, so these aren't the actual springs I used. But, you get the picture.
Like so:

Then take your band saw ( or dremel, if you prefer to be messy ), and cut off the handle, ammo holders and cocking handle of the NF, then with your dremel, widen the barrel hole on the front enough to accommodate a coupler.

For some reason, I must have huge couplers where I live, because I couldn't get it to fit in the plunger tube at all. So I had to grind out the outer edge of the coupler to fit over the plunger tube. Once it fits properly, Goop away!
Finished NF:


Act 2: The Brain
Take your Lbb, open it up and cut off the orange stock barrel.

Then take 2 couplers, a length of 1/2 in. pvc, and a length of 19/32nds Brass. You have to make the the couplers and PVC long enough to be just beneath the barrel hole of the Lbb. If you've got it figured out, make sure to hotglue the couplers and the PVC together. If it leaves you a little confused, just wait. There's a picture of this assembly in a bit.
There!

Then take your band saw, and cut off the entire trigger gaurd.

Finished Lbb:

Act 3: The joining

If you cut off the trigger guard of the Lbb, there should be a rectangle shaped box on the underside of the Lbb near the front just begging for something to be put there. And if you put it there, and cut off the cocking handle, the plunger rod should just fit right before your hand.
After its been secured there, Hotglue the crap out of it.

Finished sexiness:


With an 8in. brass barrel for the lbb, and a 3in. brass barrel for the NF, this is what turned up:
Nf: 58ft, 61ft
Lbb: 91ft, 96ft
I didn't actually do the 19/32nds nesting part, because my crappy adhesive skills, but I'm pretty sure that would put the Lbb ranges into the 100s region. I also found that you can fire the NF in two ways. 1) Angle it up a tidge ala M203 style. 2) flip the entire blaster upside down, and viola! you have a NF-like rifle.
