I haven't been able to find a definitive answer.
Can I use 15mm end caps to convert DT 350 20x110 boost hub to "regular" 15mm boost standard?
I'm guessing so, but with all the "standards" out there it wouldn't be odd if somehow 20mm boost has different spacing compared to 15mn boost...

Dt Swiss makes adapter end caps.
But you don't really need new end caps.
Something like this should also work.

Make sure that you have enough space on your fork lowers to run the bigger end caps that 20mm axle hubs are equipped with. That might be a hurdle if going for the 15->20mm sleeve rout.

From what I remember when I looked into it the DT350 hubs are not convertible, only the DT240, but look it up on their site, a few minutes of research will tell you.
But I'm pretty sure I"m correct about that, because when I was deep into it 2 years ago for a new wheelset, I ended up buying a Hope front hub as it was the best affordable/performance option for a convertible hub. But its possible the DT adapters do exist I just couldn't find any or they were too expensive.Anyway just look up the hub accessories on the dt swiss website.

Adapter axle

Thanks, this looks very affordable and easiest route to go.
I wonder if I could use stock 20mm axle on Durolux with 15mm QR?

Edit, I've measured the dropout on the Durolux to be around 20.8-21 mm.
This means that I could perhaps fit that axle reducer and use it as a sort of a dropout for the fork. I would still need to engineer some sort of bearing cover that will go over the axle reducer and between the hub shell covering the bearings.
