You can do this build in support too. I wouldn't recommend, you would be really squishy for support, but do what you want.
If you want more cooldown, but I wouldn't recommend since you already have a lot of cooldown with this build and you would be loosing a lot of wave clear, which is not really what you want in solo lane.
This is up to you, if you want cooldown go with Chronos Pendant, if you want movement speed go with Gem Of Focus.
