Unfortunately those "short reach" or adjustable levers can't repeal the laws of physics. If the lever is made to sit closer to the grip, then you will have less travel of the master cylinder piston when you pull the lever, which will then mean less travel for the clutch release mechanism. Less travel at the pressure plate means more clutch drag, which will affect shifting.
The problem doesn't really go away on a cable clutch either when you modify the lever or use one of those aftermarket "easy clutch" kits. You are still trading clutch release travel for lever effort; it's just easier to disguise the issue on a cable bike because of the freeplay adjustments available on a cable clutch. Eliminate enough freeplay to make up for the lost travel of the new lever or easy clutch mechanism, and you can easily create a slipping clutch problem and premature wear.
I fully understand the issue of small hands and the reach to the lever, because I have relatively small hands and short fingers myself. If there really was a way to make one of the short reach levers work on a hydraulic clutch, you may rest assured I would have done it long ago.

Oh, btw, the Assist & Slip Clutch only comes on the CVO and Trike bikes, not the 103 models for 2014/2015. And all the clutches are hydraulic these days. See if one of the regular 103 models is more to your wife's liking. It's probably better to give up the CVO bling than it would be to suffer with the CVO or have to change out the entire clutch system.
Thanks for your comments Jerry.
I'm sorry if I misled anyone, but my wife is not looking at the CVO Limited... She is looking at the regular Limited only in the Low model.
She is 5'2" and tips the scales at 115lbs (soaking wet) but she sure can handle her '06 Ultra like the best of 'em, and her '97 Ultra prior to that.
I'm very proud of her and how she has graduated over the years starting out on a 250 Honda Rebel for 3 years, then a Dyna Low Rider for the next 5 years and then took over my '97 Ultra when I purchased my '05 SEEG.
She absolutely loves to ride and now that her '06 has so many miles on it, it's time for a new bike and she really likes the '15 Limited Low, except for the tough clutch! Her two previous Ultra we equipped with H-D lowering kits front & rear, so the Low model is perfect for her, plus all the improvements since 2006 is a real treat. We just have to figure out the best way to make the clutch easier to operate.
She also has a Deluxe but with the custom paint job and special signature on the tank, she doesn't ride it too much - just for short day trips and to shows. We do a lot of touring and for her the Ultra is the only way to go and hopefully we get this clutch concern figured out for the 2015 or we'll be looking for a used Ultra with low miles on it, but that is not our preference only a compromise.
Here she is with getting her custom painted Deluxe autographed by her childhood heartthrob a few years ago.
