It would work, but it would not work correctly.
You need to keep your toes away from the front, yes. and correct width with good lacing can do that, along with an insole if the shoe is too tall or wide for your feet. Adding another pair of socks would also help, but often allows your feet to slide around inside the shoes....not good.
To keep you heel anchored, depending on the shape of your foot, your footbed should not be raised too much, as you'll raise your heel above the shoe's heel cup, and heel lift can be an issue. Solved with high tops.
Bigger shoes can also be too wide in some part, like the heel, the forefoot, or the instep. Fit is important because you're not only running forwards and backwards, but mostly laterally. Correct lacing should usually fix that.
But longer shoe, something you're not used to, can cause you to trip over the toes of the shoes when changing direction....not the best for grace and precision.
In the end, we get used to almost everything, so it worth the risk, if the price is good enough.
