Jacobs Ladder, is a steep ascent, however, the descent on the western side of Kinder, while steep and semi stepped, is manageable in dry weather, but can be slippery when wet!
Another route to consider is Oaken Clough, from Edale Cross down to Bowden Bridge (where the Mass Trespassers met April1932) is a decent hard core agricultural path/track.
William Clough might be a better choice, the ground will be a bit more solid than your planned route. William Clough has a decent gradient, it follows one of the tributaries that supplies Kinder Reservoir, which will involve some water crossings.
