Ok so if I do a zj alt swap and I move it to the ac compressor spot do I put an idler pulley in place of the old alt spot or do I just put on a shorter belt?

Why not put the ac compressor there. With a little fab you can make it work.

I guess I could do that

Keep us posted man. Take pictures. This is something I've been thinking about doing. Let me know how it foes.

Will do... I might attempt it this weekend
