As I see it -
1. There's no point in using a TS-E lens without a tripod, so reducing the size & weight of a TS-E lens would be negligible.
2. There might be some IQ benefit, but TS-E lenses are a niche market, which I guess is why Canon didn't make any TS-E lenses for specifically for crop sensors. I've heard the 17mm TS-E lens was introduced to be a TS-E 24mm equivalent on crop sensors, but it's still FF compatible.
In short - if there's money in tilt-shift lenses for EOS-M bodies, Canon (or some other lens manufacturer) will probably make some. My guess is there isn't any, so there wouldn't be any.
The most obvious advanatge to me seems to be price, a specialist TSE lens on a EF-S mount would still I'd guess come in at around $1000 or more for a manual focusing prime.
Question is how many photographers would like to buy a lens they would have to upgrade when upgrading the camera.
I'd guess a TS-E adaptor could be significantly cheaper than that and could be used with multiple lenses that would still AF when used on a DSLR or with the regular EF adaptor.
Canon's TS-E lenses do not autofocus. The electronic contacts are used to control the aperture & record EXIF, but focus is still fully manual.
There does seem to be an increased interest in using selective focus via tilt recently which could be capitalised on with such a product without damaging the market for more serious FF specialist TSE lenses.
Like the lensbaby, only with better optics & electronic contacts?
I actually thought of buying a Lensbaby Edge 80, but the price is too high, at least for what seems to me like a semi-toy.
