I recently had double-front interior oak doors installed in our home. We had the same dilemma as you when it came to matching the stain for the door to the existing trim in the foyer.
Our installer worked with another professional that was able to custom-mix ANY color we wanted. This is we had the Stain-Man do. We had him make us up about 1 quart extra for future use too.
My best to ya and hope this helps. Oh, by the way, you can call floor installers or wood-door installers to see if they, or someone they know can make custom-finished stains for you.
