ISIS w/ External Bearings for replacement?

I've got a set of Raceface Turbines with an ISIS bb that's churning
its way to oblivion. Does anyone make an external bb that works with
these cranks? I found this:

but I think it only works with new versions of ISIS splined cranks.

The manual says "Compatible only with Howitzer system crankarms". Even
if a standard ISIS crank fits on the spindle, the chainline will be off
and the tread will be noticeably wider.

ISIS and external BB , 2 piece systems are not intercompatible. Get
some spare ISIS BBs or new crank.

Yeah, I thought about that. I guess the interface point on newer
versions of the external ISIS cranks are much narrower?
