I'd love to try them, see if they are more rigid, and yeah... save ~50g 
I'm still a bit sceptical on 2 aspects.

The carbon spokes, how easy it would be to find and replace a broken one where you ride.
A no holes rim to avoid the tape is not possible with them.

Then the hubs, I prefer to stick to a known brand especially DT-Swiss.
Multiple times they saved me with their available range of free hubs or end caps.
To service them, or because of an order mistake, or to reuse the wheels on another bike or changing the transmission brand.

That said, only a few bikes I've built, came back with broken spokes, and carbon ones should be stronger.
Hopefully they designed the hub to have a single size, so 4 spares would save you in most cases.
Using a steel spoke temporarily should be possible too.

Riders who change their transmission or want to reuse their wheels on another bike is not that common either.

Did anyone try already an XT M8100 crankset on a BB92 frame like this one ?
A 32T is touching the chainstay.

Did you have to put a shim to get the chainring a few mm out ?
When I try this. The spindle is a bit too short than usual to tighten it.

Is something wrong with me? After watching this Dogma F12 build video...I almost wanna build a 218 myself 
YouTube Title: Dream Build Bike Pinarello F12 Shimano Duraace Miche Wheelset made in İtaly

Thanks for sharing this nice video.
Mounting the handlebar reversed first is a great idea !

Did you get any response from Tideace?

I repaired a few frames already, but failed once around the seattube, as it was not easy to wrap it well because of the other tubes around.
As it is a quite solicited zone, it cracked again.
Good luck in trying, and send us pics !

What is your budget ?

I am considering solving the problem by drilling a couple of small holes in front of BB.

I drilled most of my frames, and through the alloy BB shell if any, as water can accumulate inside too.
A single 1.5mm or 2mm hole is in general enough.
Remove the crank and look for the lowest point of your frame where you park it usually, and drill there.

... factor in costs for tools you may not have.

Building your bike put you on another level.
Many of us started to build their first bike with very limited tools.
A multi tool, with a chain breaker, while not the most comfortable can do a lot.

Then you need a BB tool, either a very cheap M12 bolt + washers for Press Fit, or a Shimano BB if you go with a threaded BB.
And a cassette removal tool.
Aliexpress sell all these tools very cheap too.

If you don't have a torque wrench, tighten the screw gently, and if the thing moves, tighten a bit more, but never too hard, until it doesn't move.
