New XTR/XT/SLX 12 speed on ebikes

[Pyr0]

I've recently been thinking about switching to Shimano 12 speed on my Levo, but using the 10-45 cassette.
What chainrings are people running?
I've spotted a raceface SHI 12 ring but it's only 34t and aluminium

SHI 12 Chainring – 104 BCD

If you're looking for a bomber new chainring that can run with your Shimano 12-speed drivetrain, then look no further. This ring, with our NW tooth profiling can bolt to any 104 BCD spider and is stiff, turning all your "push" into straight up "go".

And the wolftooth HG compatible ring

104 BCD chainring for SRAM and Shimano Drop-Stop wide/narrow sprocket

which comes in different tooth options, but is still alu and costs twice the price of the raceface ring.

Are there any other options available?

Is there anything else I need to consider?
Would I need a new derailleur hanger or should the existing one work?

Hi Pyr0
As above i use a 12 speed shimano setup and had issues with the stock Specialized chainring so changed to a Wolftooth 104 BCD 32T Drop-Stop ST which is designed specifically for the purpose and works great. Its aluminium so may have a shorter life than steel ring but so fare no issues.

I currentely ride 1x11 GX with 11-42 cassette and when this wears out I'm pretty sure I will upgrade to something with more range, especially I miss bigger cogs for longer&steeper climbs when also turbo mode is starting to struggle. This Shimano 12spd XT drivetrain looks very interesting to me, especially on paper and many reviews on acoustic bikes, but almost none with ebikes, Shimano says complete 12spd range is ebike rated, also latest Levos come with this drivetrain so I think it has to be somewhat good ar at least ready for ebikes. I'm wondering has anyone here make same swap (GX 1x11 to Shimano 12spd) and has ridden some distance now, have you any regrets swapping to 12spd? And how its durability comparing to 1x11?

One thing that interests me about the Shimano cassettes is that you can replace the smaller sprockets when they wear out instead of changing the whole cassette
