I know you joking, but I figured I'd respond seriously, with only produce a $35,000 there would be a much lower volume of sales. With fewer cars to spread fixed costs among, cost per car would climb drastically. The price would have to go up.

2) Add a secondary energy regeneration device downstream of the exhaust. Ideally something like a variable vane turbine on the front side of the motor. At a steady state 70 MPH level road cruise 8-9 HP could be recovered from a turbine - which would bump gas mileage to an honest 30 MPG.

OK, just look at the other mazdaspeed models, theyr starting price is the same as a fully loaded normal model, you could expect the same for a MS8

It only cost about $1k more than a Miata LS.

Probably very very few, if any.
No other cars in Mazda's lineup had the same turbo BP engine (BP-4W, not BPT). No other cars had the same clutch, suspension, transmission, interior bits, etc. The NB Miata was on a unique platform and shared few parts with other Mazdas, the Mazdaspeed NB even fewer. In fact, Mazda's marketing literature for the MS NB claimed that there were several *thousand* changes.

People have mentioned all aluminum. I would think Mazde would have already done this if it were possible. They spent a lot of time and effort (read money) working on seal materials to allow for the heat expansion differences between the rotor housings side housings and rotors. If all could be made from aluminum, i think they would have done it.
The flooding issue could easily be solved by ECU timing, without even warming the engine up. The car could rev up to 3000 rpms, and the the ECU would simply shut off the fuel. As the engine slowed doen to a stall, the air moving through would dry out the cumbustion chamber. it would be a pretty cool affect, to have the engine rev itself as it shut off.
I would love a next gen RX8 with similar overall design, 200-300lb less weight, and 10-20% more NA horsepower. I'd immediately trade up, even at a premium unincented price.

I have this idea, a larger center housing, with aux ports and instead of siamesse exaust ports two ports just like the ones in the side housings, instead of 6 intake ports 8 intake ports.

if mazda starts offering rotary electric hybrids, then we will start seeing some real changes as they can spread the cost out among many models.
they next rotary will be DI and all aluminum, I would bet money on that.

That's what I've been hoping for, wonder what the real world gains in hp, weight savings, and fuel economy would be. For the uninitiated some kind of easy oil read/fill option would be helpful. I honestly wouldn't change anything else on the car, except offer the GT without a sunroof (like in Canada) and a better radio/USB/mp3 and a dashboard readout that doesn't look like a 1970s digital clock radio.

mazda already has prototype rx8's with a different rotary engine and tranny but in present rx8 exterior form driving around vegas, theres 3 i seen there all ti grey w/small blue stickers on the fender that look like a bar code, i talked to mazda rep and told me that they were 2010 motors that they are testing in the heat.i asked if i can take a look at the engine but he said he couldnt do that. 
also theres a black twin turbo rx8 sitting in mazda corp irvine that also is a prototype.

If ZOOM saids it, its almost oficial
ill tell you what i heard today from what i consider to be a credible source-
you all know how dedicated (possibly "obsessed") the rotary engineers are at Mazda- often working on their own time like during the "creation" of the renesis. Well they have apparently again been burning the mid-night oil on the "renesis 1.5/2.0 project" to the point that some of them were quite clearly exhausted. So Mazda has given them all a mandatory vacation for a little while.

I suspect we are going to see a revision to the engine in some way before the end of the RX-8 lifespan/generation. I don't think we'll see any dramatic power increase but I bet with the problems that people have had that we'll see some form of an updated oil metering system.
