Sorry but no, EF-S lenses are designed for APS-C sensors and can not be used for larger sensors. EF-S lenses extend further into the body therefore the larger mirror on an APS-H or FF would hit the back of the lens. EF-S lenses also produce a smaller image circle designed to cover an APS-C sensor only.
Perhaps its not clear in what I wrote. Let me elaborate.
In-camera crop on an APS-H sensor to use an APS-C lens isn't too far of a stretch isn't it ? The mirror of the 1.3crop isn't that big compared really and with some tweaks, it may fit an EF-S lens.
There was a story / article of a guy who did something of the sort with his 1D and mounted an EF-S lens, albeit with some minor modifications to his lens only. The height difference between an APS-C and APS-H is less than 5mm.
So, it might be possible to tweak the mirror in an APS-H camera to have sufficient clearance for an EF-S lens' rear protrusion.
Thus an APS-H camera with an APS-C crop mode by allowing it to accept EF-S lenses. Especially if the AF module was designed for APS-C in the first place. Possible ??
I think its physically possible to do and then why not consider making it mirrorless! no problems with mirrors hitting lenses anymore.
also not sure how many here have used nikons but say you put a DX18-200 on a full frame FX film body you only get very severe corner vignetting not unlike what the tamron 18-270 delivers that people seem to put up with. on the FX digitals the electonics crop it to 1.5 for you so you dont get that.
Even using the APS-C EF-S lenses on the APS-H sensor would only result in some corner darkening anyway then let the user crop as desired
I think an APS-H with APS-C in camera crop that can use EF and EF-S lenses would be cool especially if you get boosted frame rate with the APS-C mode too. If that was canons entry to the mirrorless segment it would set the bar pretty high for the sonys and panasonics to chase and the nikon v1 and j1 would be outdated instantly
