I'm looking for a clutch lever that's easier to pull than the stocker. Between the distance and the amount of force needed to pull the stock lever it's wearing me out.
Can't fit anything longer in there, so I don't think you'll get an easier pull with a different lever. Is your cable partially seized? Mine is an easy pull.
I'd start by using some Teflon lube down the cable from the clutch lever end. Also be sure to use a small amount of white lithium grease on the cylindrical end that sits in the lever itself, that's a very common bind point for the older-style cables.
Ducati changed out the clutch cables somewhere around 14/15 to use a plastic sleeve around the metal slug on the end of the cable to prevent seizing and subsequent cables breaking.
I replaced my stock levers with a pair of Adjustable Ducabike levers.
They work like a charm. This may help with the lever reach but you will have to adjust your clutch cable to set the disengage point to suit your riding style.
They cost a lot but I liked the look and the quality........
Check compatibility with your exact Brake type before you buy.
I don't know what you mean by clutch perch, but you can use a variety of aftermarket levers. You do need to be mindful of compatibility for the brake plunger. I'm running $40 ebay shorty levers that are awesome.
