Panel rear drop springs and 15 inch wheels

[CG]

So I have Burb/Panel heavy duty 4 inch drop springs on my panel. I was looking for a 6 inch drop so I also added 2 inch blocks. When the shock relocating brackets were installed they are just a tiny bit below my scrub line.

Im running 15 inch rims and want to keep it that way. I was thinking about getting rid of the heavy duty Burb/Panel springs and two inch blocks and installing 6 inch drop truck springs instead. Losing the blocks will get my scrub line back. What type of shocks would you suggest to make up for using truck springs?

In the future if the panel turns out how Im hoping, I may install rear helper bags for towing, but an all bagged suspension is not an option.
