Please read the OP fully. I address this topic in-depth, including a replay; the TL;DR of that is that it's a very bad idea for him to retreat and tech up to colossi, and you don't build hydras unless he pushes anyway.
And your way to approach this is the typical one; however, this requires very precise control and macro. If people at high diamond aren't looking at their army when they move out, I assure you that the higher you go the less true this becomes. Still it's definitely a valid way to hold the push as well. Personally I think it's more fragile than going hydra though, since you can get FF'd badly and lose a lot of army.
Also if you go hydra, you can do the same thing as what you suggest (just not with the hydras). Sending lings outside his base and making him burn FF's is a good idea if you have enough.
