Can anyone recommend a roof rack for SC Hightower V1 frame so I don't need to take bottle cage on and off each time ?
Sort of. I solved this by swapping to the fidlock bottle system rather than changing the bike rack!
I have a thule thrutide for my bike, means taking off the wheel though

Had a V1 Hightower, bought one of these: Inno
Still using it 4 years later. Brilliant and doesn't damage frames unlike the Thule ones that clamp the downtube.
I have a yakima highroad which holds on the wheels, doesn't look like it will take longer wheelbases though
I've just bought a Thule UpRide for my SC. Like you, I was running into issues with the bottle cage. I did buy a Fidlock which is not a bad suggestion, although the Thule 591/598 still didn't quite like it - couldn't get the clamp perpendicular to the frame on such a long bike. I was buying a second rack anyway so I splurged and went for the UpRide.
It's fine, it works well but it's more fiddly to mount the bike and there's definitely more wobble.
That Inno ^^ looks similar.

I have clamped my carbon frames for years with this style of rack. No issues. I don't really believe it's a problem with carbon frames and if anything I'd wager a thin aluminium frame is more likely to get damaged. The 598 has broader, softer 'jaws' than the 591 which probably helps a bit too.
I use a Yakima highroad for my XL hightower with 29" wheels (2.6" front and 2.35" back as I think that makes a little difference); it is pretty much at the upper limit for the rack but we get on without any issues.

Anyone got any recommendations for an V2 XXL hightower? from what I've read everything is too short!
Thule upride Ive used this with a xl Megatower over motorway speeds :~) and would easily take an xxl Again to frame fouling just wheel grabbing
A 598 should take an XXL Hightower, you can adjust where the arm is to fit correctly. My XL Bird Aeris fits in one and must be similar length
The Inno i mentioned fits a Pipedream Moxie Longer model with almost a 1300mm wheelbase easily.
