Just want to do some public brainstorming, folks feel free to chime in.
A million T50RP drivers with v-playmate knurled technology.
I forgot to mention the waffle diffusifractor.
Well... Audeze did something similar with LCD-2 drivers...
Easy on the memes guys, I'm not as young as I used to be.
BA line array, by my calculations, for 6' x 2' speakers, you only need 345,600 BAs.
With a Knowles SFWK you do get 104640 BA's for each panel, for a total of 209280.
Since it's actually 2 drivers per package, that's actually 418560 diaphragms.
Guess it'd be sort of like having thousands of small mice coughing trying to get a hurricane going.
How about a CBT36? Ti Kan has a fantastic build posted on his forums. I'll dig up the link later if no one beats me to it.

2K USD in parts + tons of labour.
Shipping'll kill if I ever try to get it to SGP.

edit: oh shoot, Grahad beat me to it!
You can use Grado drivers
I really like the idea of using full range ribbon tweeters
Ala suicide by Grado.
Probably sharp enough your corpse'll have holes riddled in it.

Here is a modular line array concept by Mark Audio. Seems like a good way to go because you can break it up into several bookshelf speakers.
I do like those Hivi drivers
Rick Craig (Selah Audio) has designed a whole slew of LAs, both pre-built and kit form.
Pics for clicks:
Well, there's enough of them that if some of the drivers fail, we won't notice.
I have two pairs of the 4" Fostex drivers. Maybe a stack of those and with some series / parallel wiring trickery, make a speaker with a 12 ohm load which would be easier for the SET or PP tube amp you are working on. A four inch hole saw works perfectly. A solution that could compete with horns in terms of macro / lack of compression / low distortion, but yield less "horny" sound.
Maybe not a full LA, but something like this:
T can be a ribbon isodynamic like this http://www.parts-express.com/hivi-rt2c-a-planar-isodynamic-tweeter--297-406 to prevent weirdness in vertical polar response. The HiVi tweeter can be crossed over very high up. Maybe 6kHz since the Fostex 4" are so well behaved.
BG's NEO3PDRs are super nice for the money for that type of implementation: http://gr-research.com/neo3.aspx
I'd have to dig for the datasheets, but polar response is excellent, and GR has some .dwg files to cut some better waveguides somewhere...
Another plug for the CBT36, i got to hear it at RMAF and it was jaw droppingly good..dB
