Any reason rear leaf springs cannot be powder coated?

Powdercoat is probably not flexible enough, and will likely start to crack and peel.

Actually powder is MORE flexible than paint.

The only reason powder would crack and peel is due more to insufficient prep work (i.e. just roughing them up with a ScotchBrite pad versus media blasting), a failure to clean the metal after blasting, and/or under- or over-curing it. Just like paint, you can spray it on any untreated surface; how long it stays there is dependent on whether the metal has any "tooth" for the finish to adhere to.

The biggest reason I won't coat them is because most people won't replace the Delrin liners or take the time to disassemble the spring packs to do it right.

One of the Morning Coffee crew had his leaf springs coated recently ... and regretted it. The place coated the springs completely without taking anything apart. Not only will they now not operate as designed, along with the receipt for the "work" they gave him an apology ... because the Delrin 'liners melted and ruined the finish, and made a big mess out of (his) oven.' If I remember right they gave him half his money back ... maybe enough to buy another spring. :elmer:
