I have a Lenovo Tab 2 A10 or something like that at work so it would be a 10" screen, but unsure on the exact width of the tablet instead of diagonal measurement.
Either way, it BARELY fits into the stock
P4P controller mount. I had to really push to get it to compress the little foam strip and fit inside.
I think this tablet has fairly thick bezels so if the Ipad is super narrow it may fit, but I would lean towards no.
I think I saw some simple extension piece you can buy to fit larger screens though and wouldn't really be considered a mod, just an accessory.
