I'm rather surprised to hear of a 11/17 freewheel. Do you have a photo of it?
DNP Epoch makes an 11-28 freewheel.

It preserves your 11T high-end, and is rather relaxed on the low-end.
Expect the freewheel to run a little wide for a 7s freewheel.
Personally, I thought it had too many jumps for the smallest sprockets, 11-13-15
What are your GF's favorite gears on here current cluster? What is the highest gear she regularly uses? I would use that as a guide for picking out a new cassette. If she rarely uses the 11T and 12T, then there is a much larger selection of 13T freewheels.
