JK Control arms as a mid-arm setup

[L0jik]

Im putting a Dana 60 rear in my Jeep and I have a chance to get a set of rear Rock Krawler X- Factor arms for dirt cheap. They are single adjustable mid-arms for a JK. And I figured since I'm doing bunch of custom work for the Dana 60, I was considering putting these arms in. The lowers have a suggested length of 20" and the uppers have a suggested length of 17", putting them between 3-4 inches longer than stock TJ control arms. What are the thoughts of the suspension gurus? Could I move the control arm mounts on the frame and run these?

The control arm mounting locations create the suspension geometry. Arm length is a consequence of the mount locations. If these arms are of a length to connect the points between points, then they will work.

Rubicon express jk lowers unmodified.
Front uppers were used in the rear upper position by adding a stock jk front frame end bushing to the non adjustable end. Stock frame mounts were relocated.

Unmodified front Rubicon express jk lowers. Front upper 3 link is 2x.250 Dom with a stock upper axle end and trail gear creeper joint on the frame mounted in a jeepwest 3link frame mount. Axle bushing is a jk moog replacement w/12mm 12.9 bolt. This rig was done almost 10 years ago.
3 years ago, I built new arms for it with currie joints and added jeepwest rear upper axle geometry correction brackets without changing anything else which got rid of some body roll and bobing.
