In a word, yes. In fact, after talking to Roger@UDC for a week about bearing issues, even having bearings shimmed up isn't the best solution. I would assume the bearings you have are the 40mm Profile standard bearings, and you've just got a frame (the Summit) that has 42mm holders. The best solution would be to find a set of bearings that are 3/4" interior diam and 42mm outside diam.
I know (thanks to Roger) that the KH/Onza hubset has bearings that might fit, and thats with an internal (inside instead of outside the bearing) shim. Might be worth contacting UDC about getting some different bearings that would fit.
cut a shim to put around the bearings from one of dads beer cans.
dont use a Guiness can since thats a dark beer and therefor your uni will be heavier....go with Bud or Busch light cans.

For trials, I would go with the Guiness shims, as they will be much more Stout.
You should be more concered about what the too small bearings do to your frame than about bearing damage. Tightening the bearing holders down on a smaller bearing will deform them, and running them loose will wear them so that they won't fit the correct bearing later. The bearing is much more replaceable than the frame. Shimming is fine if done properly.
