Of course, tweed is more of a less formal, Fall fabric. Just like kilts, the heavier the fabric, the warmer it will be. Anything between 5 - 18 oz, like I said, more or less, depending on the temps you expect to typically wear it in.
I'm in middle Tennessee, so weather wise 90's in the summer and 40's in the winter. It would probably get most use in the summer. Then again, why make one when you can make two for twice the price...warm weather jacket and a cool wether jacket.
And it is the less formal look I was going for. Although I did like that charcoal jacket and vest Graham got a while back, you could almost pull off a formal outfit with the right accessories.

There are a number of sources for wool suiting on the web though, at anywhere from $5 - $30/yd (or more, if you want the high zoot super wools). denverfabrics.com is a good place to start. Google wool tweed fabric and you'll come up with loads more in all price ranges. If you can get swatches, that's a good idea. Denver Fabrics has them for $1 and free shipping.
Have you seen the tweeds at http://www.thescottishweaver.com/ ?
They are light weight. Just don't know how light. I was wandering can a material be too light for suit jackets?
