WRT the wheels, you probably don't need an adapter, you may already have an adapter - from 15mm to 9mm. To find out if you do, just take out the QR halfway, and see if you can push it cockeyed, then whack it with a mallet and see if the 9mm endcap pops out leaving you with a 15mm thru-axle repeat on the other side and you are good to go.

Hi Epic,

I checked out the front hub, and I don't think that this will work.  The hub is designed as follows:
 the sealed bearings are covered by dust caps; the dust caps are held in place by nuts which  thread onto the axle; these nuts are in turn held in place by outer lock nuts; and the QR skewer runs through the whole thing inside the axle.  The whole arrangement looks somewhat like an updated version of an old cup and cone bearing hub assembly. 

Taking out all the parts which would be incompatible with a QR15 (ie. the axle, dust cap nuts and the lock nuts), leaves just the thin little dust caps and the bearings.  Unless I am misunderstanding how the QR15 system works, and I am totally missing something in this picture, I think I definitely need an adapter.  But all my searches on the web have not turned up anything for this model of Crossride, so I don't think such an adapter exists.  Unless I want to swap the hubs or the whole front wheel (not going to happen), it seems I am stuck with 9mm QR. 

On an up note, I did discover that the travel on some XC forks can be changed from 80mm to 100mm with the use of a spacer.  So if we go with 100mm, and the bike doesn't feel right, then we can easily switch back to 80.  Nice!
