I think I can use this PID controller:

To control an outlet that I would then plug in my 1500W Hot Rod Heat Stick
(that I already have):

Then re-purpose my 'spare' immersion chiller:

Using my Solar pump and PWM to move the mash water:

In a 5 gallon pot I already have.
I use a 52QT cooler as my MT that only loses 1deg an hour:

Drilling a hole in the lid for a return wouldn't be an issue but I was thinking would it be better to return through something like this:

Instead of just dumping back on top of the grain bed to avoid compaction?
This would basically cost me $17 to get up and running since I already have most of everything. But since I already infusion mash and batch sparge, what would I gain by recirculating my mash through this constantly?
Clearer wort I would guess, but does that have much effect on the finished beer? As quoted in BYO magazine "If the mash is not stirred, the constant recirculation of the wort in a RIMS/HERMS eventually yields crystal clear wort. This is almost always cited as a major benefit of brewing with a RIMS or HERMS. But why is super clear wort a benefit at this stage? Most articles or Websites discussing these systems are silent on this point. The claim that crystal clear wort is better wort is taken to be self-evident. I did find one site that claimed that part of the cloudiness in ordinary wort was due to lipids, and lipids in beer lead to premature staling (which it true). But does the crystal clear wort that comes from these systems really yield better beer than the slightly cloudy runoff common to most non-RIMS brewers? Like the claim of repeatability, this has never been tested.
Another question to consider is, does the recirculation of wort in a RIMS or HERMS clarify the wort too much? Studies have shown that a small amount of lipids carried over into the fermenter helps with yeast nutrition. You can argue the point either way — that’s why claims need to be tested."
Will it improve my efficiency? What other gains might I see? Would I need the Loc-line since I mash thin at 1.5 anyway?
As Quoted in BYO magazine: "RIMS and HERMS machines do perform as described by the folks who brew with them. They hold mash temperatures constant and produce clear pre-boil wort. The claims of how these affect beer quality and repeatability are untested, however. But the big question is — do RIMS and HERMS make better beer than “ordinary” all-grain methods? This again would take a fairly large and detailed experiment to answer, but we can look to homebrewing contests for an idea as to how the experiment might go. If brewing on a RIMS or HERMS inevitably led to better beer, we would expect RIMS and HERMS users to hog all the medals. On the other hand, if RIMS and HERMS could only produce thin, headless beers, these brewers would be crying until their PID controllers short circuit after the medals are handed out. In reality, neither group dominates at homebrew competitions. In the hands of a good homebrewer, a well-designed recirculating system can yield great beer. In less capable hands, it can result in a wort that goes round and round. "
So in the long run.. am I just getting excited to add another "Toy" to my brewing? Hmmmm... Maybe since I already get great control of my temp loses and don't step mash, I shouldn't fix what isn't broken.
