I'm working doing the exact same thing for a couple years now.
My project though is a little more humble. I'm using low power motors aiming for range and lightweight instead of speed and power.
heres the preview:
hope it motivates you on your project.

The bigger wheels are much more suited for speed and road imperfections.
Fewer faceplants maybe.
Maybe easier to add a motor also.
Only downer is that a lot of the popular sizes are sold out. Can find some on ebay. Rumor is a new improved 2015 model is coming out.

I finally registered here in ES, but I have been reading this forum for a while. Truth is since I started building the ThundrBlade I've looked everywhere in the internet for information. I even checked patents for info.
About the LandRoller suggestion, I had Land Rollers before. they feel different from normal inline skates, they are good, practical and a lot of fun, but not the same maneuverability. I dont think you could make hub motors work diagonally like that. maybe it can work. I dont know.
You could use the motors elsewhere and transmit the power trough gears, but that would add a lot of noise.
well, I expect to build a new prototype with double the power in 1 month or so, I will make new clips as I have progress.
ps: I love the powerslide open boot design, mine are not doops, but they are from the Nordic Skating but they are very similar to doops.
ps2: I gave up on using UFS and went for a normal 165mm mount, I think for a product its a better choice.

I want to run the 85KV by itself (because it is compact enough to fit like a hub) but I thought also of planning low KV in bigger outrunners which should be belt/pulley-driven, so for mid-drive you do recommend a mid KV not too low? I was thinking of something around 130Kv, is it already too low or with proper gearing do you think that it is ok?
Just go hub all the way my friend, especially now that you have connections with the motor manufacturers. It's the way of the future. Don't worry about the low kv, just slap higher voltage on them and they will tackle anything. The formula of low kv motor + higher voltage has been proven on E-bikes, and gives you the whole range of performance from low speed to high speed. Higher voltage also give you more range, just look at Boosted's range of 6 miles on 2500mah batteries and dual motors. They get that from the 40 volts.
Higher voltage does not give you more range. It's slightly more efficient then a low voltage setup but that's offset by the cost of high voltage esc and high voltage chargers. Boosted's 6 miles on 2500mah at 40v equals 16.7 w/h per mile which is about the same as other e-boarder with their DIY builds. The e-bike guys who use rc outrunners get similar watts per mile as well.

I wan to use those dimensions to make my geared hub....
Btw, where and which manufacturer you sourced it from? How much was the surcharge you mentioned?? I wanna just order it and pay for the surcharge....desperate and impatience here....

I'm an old school rollerblader and I've been messing around lately with newer frames and big wheels. I'm not sure how I would do it without it getting unwieldy, and I can't wait to see your implementation.
P.S. I've been rocking the Razors genesis skates which are basically the exact same as the M12s. I want to get a set of Xjsados soon too though for powerblading / Big wheel setup.
Where do you plan to mount the cells?
P.S.S. What are those clear UFS frames? Did you make them? Most of the frames That I've seen that are that large are made out of metal, I'd love to try them out.
