With a chain length in multiples of 31 only (so it will have to be 124 realistically) ... then a whacky mech to keep chain tension.....

Not sure how you make a narrow wide 31t though?

Boost+ standard 155mm rear spacing.
Front: 1 floating 31t Narrow-wide chainring with carbon spider and steel teeth, to achieve optimum chain line according to the sprocket chosen on the rear. Say 55mm to 44mm?
F.e.: If you shift from the 9 teeth sprocket upwards to 48 teeth, the 11 sp-chain will exert a pulling force on the front chainring and thus move it to the optimum chainline and vice versa.
If the floating chainring is hinge-carried instead of moving on a kind of 'rail', it should be less prone to dirt.
This setup should save chain and cassette life.

PS: I guess you are also on the Chinertown forum

Not on a hybrid. The e-CVTs are are an amazing piece of engineering.
