deeper splines will either reduce the bearing and ratchet size/radius, or increase freehub size, which will reduce possible gear range...or both.
recent trends have already reduced bearing/freehub diameters, btw...
such engineering compromises always have consequences...... like increased loading of the spline faces, or the previously mentioned gear ratio selection reduction.
we're seeing 10-50 range of rear gearing now... the increase in spline size would push that to 12-56, or so, and a change of front ring to a smaller size to compensate.i'd guess.... front ring wear then accelerates in response........ so everyone swaps back to two or three front rings, and smaller cassette ranges.. negating the weight loss of the new cassette/hub combos...
the bike gearing merry-go-round will need zerks on the bearing assemblies.
The changes to support the CF cassette base body with steel ring gears would likely change the design so much that it would not accept what is already in production (WRT hub/cassette) across the world & look very *unique*. That doesn't mean it couldn't contain an 11T cog or a 46T cog, that would fall back onto the OEM to offer such cogs within the range they're willing to produce.
I personally wouldn't consider it, unless the design went to something crazy like 1x15 & included sleek mechanical road shifters with integrated hydraulic braking while still using the 12 speed chain specs.
Innovation is a thing.
