I've debated doing the same thing with my 2010 Giant Trance, which also has a 44mm headtube. You can supposedly use a 1.5 bottom cup on the bottom and keep current top, but my Trance has an hour glass shaped headtube with very little space that's actually 44mm. If the headtube was straight, I'd say no problem. I'm curious to see if anyone has pulled it off.

You should be able to do it. I even with an head tube which isn't straight. If you run a standard 1.1/8 upper and a 1.5 lower. If you haven't got the space to set the lower into the head you can always run an external cup on the bottom.

As for purchase, I've brought from works components before and they will mix and match for you to get it sorted - if I remember correctly they have a section for giant and the different head tubes that they (giant) have.

No, as far as I know you cannot do this. You can run a Straight 1-1/8" in a tapered or 1.5 " head tube with the use of a reducer head set or reducer crown race. I did this with my 2010 Reign x2 which had a tapered head tube. But pretty sure you cannot run a tapered fork in a head tube made for 1-1/8.
As for the comment below about using an external head set on the bottom, giant uses a Semi-integrated/0 stack head set which means you cannot use your standard external head set. maybe you can modify it, but i think it would not be good to do.

As long as the head tube is straight 44 mm internal diameter it should be compatible with 1 1/8" straight or tapered. A good example is the older style chromoly Ragley Blue Pig. Another good example is the Soma Juice which actually has the 44 mm with an hour glass shape like my Giant. A few of the steel rigs have this in order to be compatible with the modern tech. My concern for the Giant is the portion of the head tube where the headset "presses" in is very small before it starts tapering into the hour glass shape. The bottom headset cup might not press all the way in.

You can:
Commencal Supreme 6 frame with 44ID Nukeproof tapered headset

44mm ID headtube (top and bottom), ZS44 cup on top, EC44 cup at the bottom.

If you have a frame that is tapered, 1.1/8 - 1.5 then you can either a straight or tapered fork. You will need to buy the appropriate headset. And I assume that the fork has a 1.1/8 steer.

I have a 1.5 straight head tub end run a 1.1/8 steerer using a reducer headset. As your frame is tapered you will just need to replace the lower cup assembly or bearing unit with one that is sized to reduce from 1.5 to 1.1/8.

If it's any help I got mine from works components.

If you're running a a 1 1/8 steerer into a tapered head tube, I'd recommend using a standard tapered head set and use a crown race adapter that'll let the 1 1/8 steerer fit the 1 1/2 bottom head set cup. This way you don't have to switch out head set cups if you go from tapered to straight or straight to tapered.

Yes, and most crown race reducers are only $10-20.

I use to have a Trek with a straight 1 1/8 steerer on it, and looked on you tube for ways to fit a tapered fork. Well, there is a way, you need to get a external bottom part of a head set, which Cane Creek makes. What you will need to do is to measure in inside diameter of both the top and bottom of your head tube, so they can you the correct size, they have a neat size finder on their website. Hope that helps.
