broken m5 front hub what now?

Depending on how you look at it I was either very lucky or very unlucky. I had just finished decending 6500 ft and was braking to a stop at my vehicle when I heard a cracking sound and my front wheel skidded to a stop. I had almost stopped when it happened so I didn't go down. My front wheel was badly out of true and rubbing on the brake pads. The hub flange had cracked off expelling three spokes! The 20 hole m5 hub was laced to an edge 25 carbon rim. When i got home I carefully loosened all the remaining spokes a little at a time around the rim until I had removed all the spokes. Can I reuse the spokes and rim? It's hard to tell but the spokes seem fine and the rim lays on a flat table with maybe a 1mm gap on one side of the rim.( the table may not be that flat)
I am new to building wheels and would probably have my local shop lace them up with a new hub if that is possible. Since I want to reuse the spokes the new hub must have a similar dimension to the broken M5 hub. I have measured the m5 hub and come up with these measurements. Hub flange diameter 30mm and outside of flange to outside of flange 75 mm or hub center to outside of flange 37.5 mm
Extralight ultrafront sx hub has the following dimensions : flange diameter 29mm center to flange 38mm. Do you think this hub would be a drop in replacement for the m5? Fairwheel bikes is out of stock on the hub does anyone know another US retailer of these hubs?
Am I silly to want to reuse the rim and spokes? the rim and spokes have less than 100 km and are almost brand new.
Disappointed to have broken my wheel but so happy it didn't happen while i was doing 40 mph getting ready to enter a tight curve.
