I recently bought a fancy DT-Swiss Tensio tensiometer. Yup, the

Ok, so now I have this nice tool that only comes with calibration
curves for ... wait for it... only DT-Swiss spokes. My wheels are
bladed Shimano WH-R550's, so all the provided curves are useless.

Not really. Just measure the thickness of the shimano spoke center
section and use the corrresponding spoke thickness that matches a DT
one, like the new bladed one. Or extrapolate.

No, you can't do that. The bending moment of a non-circular
cross-section
rod is highly dependent on its shape. A rectangular cross-section vs.
an elliptical
cross-section will yield vastly different bending behaviours.
