In search of an IS41 to EC34 upper headset adapter, if such a thing exists.

Would like to try a Cane Creek ViscoSet on my '18 Stache, but they only come in EC34 / EC44.

EC44 would require reaming out the frame (definitely not taking that approach).

It seems like it would be at least mechanically feasible to produce an IS41 to EC34 adapter, similar to the IS47 to IS41 lower headset adapters that Cane Creek already makes:
