Adding a centimeter of offset to the fork would not be a big job; you can still have it done, or do it yourself, without hurting the paint.

Incidentally... and I mention this merely by way of conversation, without implying that you should do anything similar: When I got my Lambert frame, complete with generic non-original chromed steel fork (the original being an aluminum 'death fork') I found the top tube sloped too much; higher at the front. So I bent a little more offset into the fork. I clamped the dropouts to a pair of bed rails using a QR and front hub, put some random piece of lumber under the bend in the fork to serve as a fulcrum, put a nice long cheater bar over the steerer, and pushed downward on the end of that. Just a little, until I overcame the initial resistance of the metal (very scientific, huh!), then I stopped. Worked fine; the bike is stable, rides nicely hands-free. And the top tube is horizontal, which is the important thing.
