It will work okay, but you will find that you have to gear up alot due to the extra gearing reduction the spiral cut diffs have. You may also find that you wear out & kill the bearings on the pinion shaft as they create alot of side-load as they spin vs the straight cut gears.

Spiral gears are better for use with just a center diff unit because you need extra reduction ( due to not having a tranny ), so it wont hurt to install them now and play with the gearing..
