One of the primary ingredients in chai latte is the tea and spices used. Since those are what typically needs to be hot, what you can do is go get one of those "multi-purpose" Keurig cups that are reusable. You can find them in the area of the store where they sell the Keurig products (often made by another third-party company).
Instead of applying coffee grounds into it, you would put the actual tea bags into it along with the spices and such. What you may actually look into doing would be to open the generic tea bags, put ingredients into that (spices and such thought, as likely not a good idea to mix the sugar or sugar substitute into the filtered cup). Then throw water through the Keurig like normal INTO a cup with your milk already in it. The B60 has an option for a very small cup (like 8 oz water) and that's what I would select. The idea is that the water will mix with everything in the filtered keurig cup and then go down into your bed of milk.
You would obviously have to experiment to get the consistency you like but you could do it this way. I'd also melt your sugar into simple syrup (over an oven range on a pan). It would mix better with the milk and filtered water. Probably the best way to do it would be have your milk bed, the simple syrup, and then mix the tea and spices directly through the multi-purpose Keurig cup, so that as soon as the hot water mixes with the milk and simple syrup you can stir immediately to mix.
Typically you froth milk onto it too for the hat but you won't be able to do that with a Keurig. You can cheat and just throw a squirt of whipped cream into it, but it's not entirely legit going that route.
I (un?)fortunately worked in a coffee shop for a few years while I was going through college.
