That sounds like a good plan. But don't knock a higher power DHT PP, they can be very good if run in class A and give a parallel SET with the same tubes a run. If you triamp then the choice of amp for the ribbon is either to be coherent with the midrange amp or to get the cleanest top octave which would be a class A SS amp with no/minimal feedback.
If you want to go with coherent tube top end you can either find a similar amp to that on the mids with a 2 ohm tap or use a Spelz autoformer.
If you triamp then the likely HF XO will be 5-6 khz which leaves the ribbon with very little to do except provide "air" and fast transient edges, which is its strength and important for imaging. The important thing is that you can probably do with just over 10 watts. Some of the First Watt designs are non feedback designs and the XM26 will be "tubey" enough to give the top end a coherent character with a SS amp ribbon amp matching the tube mid amp.
