Can I use some sort of shim to make it happen or I need to rebuild the wheel and if so, can I use the same spokes or do I need a new one (when rebuilding I would also change the rim itself). What do you think?

What make and model of wheel? That determines what kind of operation you have to do to make it work.

Maybe. I helped my friend convert his bontrager duster wheelset, rear was 12mm, front was 15mm. He bought a conversion bushing online. However I had to turn down the outer dust caps on a lathe. The OD of the dust caps didn't fit into his fork, so I turned them down by maybe 1mm? It was just clearanced to fit.

Looking back as far as the MY2017 PDF charts they have posted, 12mm endcaps aren't even listed as an option for M1900 Spline wheels.

You have to look at the hub not the wheels themselves. M1900 Spline are DT 370 hubs. This is what you need:

Talk to the hub manufacturer. I have adapters for my ENVE hubs so I can run the wheels on my 15mm Niner RLT fork and a 12mm Trek Domane fork.

I've bought 2 of these, when I built wheels for my wife and my gravel bikes I wanted to use new XT hubs which are usually reliable. With mine the front hub slipped into spot with no trouble, with my wife's there was a drip that was in the way, turned out to be a touch of epoxy but it scrapped down perfect without scratching the carbon and fit perfect. The tubes are a little trouble to fit in, have to give a real good push and don't easily come out.

There is a guy in the road forum who designed some slide in spacers to convert axles from 15mm to 12mm.
Shoot him a private message and see what he has.
