They also machine relief on the spider to accommodate the chain's outer links.

To achieve that, Praxis Works screws the chainring bolts straight into the inner ring, dispensing with the usual nut, and machines a cutaway in the crank spider arms so there's room for the chain.

So, that's almost certainly a no go. Balls.

So, next option is a powermeter that works with 3D+ cranks (or DA9000) that also somehow allows for smaller than 110bcd chainrings to be fitted.

I'm guessing Rotor INPower can't be retrofitted to my 3D+ cranks? Which means the cheapest option is an entire new powermeter crankset, which is clearly not that cheap an option. :S
