SSSWWEETT, EH!!!!!!!!!!!!
Last Saturday a cuz and I made up a body Lift out of 3" square tubing 1/4" thick.
The Body mounts that the rubber mounts sit in are a bit indented, so end up being a smidge over 3".
Used 2 1/2" Square tubing as a stearing extension (again 1/4" thick).
Took the WHOLE DAY, no 3 hour kit thing (my cheapness sometimes works against me  )
I'll try and do a write up, but thought I should put some pics out.  I was to busy to take step by step photo's, I'm not that kinda organized.

Are you guys welding extensions of your trans and transfer case levers? How about the steering extension ? 3" for these vehicles seems a little unsafe/excessive. What size tires are you running ?

I've left the plastic consol out for now, seems fine.  I may weld an extension or find some way to 'nicely' go without the consol.
I used some 2.5" square tubing thats 1/4" thick.  Bolted it in same as the 'kit' extensions fit it.  The 2.5" works great with the 3" lift.
I hope to do some fender triming and fit 33" tires.  I don't have any body cladding, so triming should be easy.  With the 33" tires 3" should not be excessive.  I used a old DIY write up for a 3" lift for a 4 door sidekick.  So far seems as safe as any body lift could be.

Dam the link didn't work

Sorry, the height comparison against a Smart car isn't very helpfull. 
The Body mounts are indented for the rubber mounts, so with the square tubing raise the body around 3 3/8".
I'll try and get a photo of the steering extension.

I think if you get an older-style Chevy S-10 shifter boot and use some self-tapping screws to bolt it right into your floor it would look and work pretty good. I've been running that on my Sidekick for over a year and it's been good. Just cover up the airbag module with something else...I used a piece of roofing rubber and stuck it to the bottom of the dash.
