I have pared it to 26 moves to solution.

Now that you've said that I wonder which way is shorter. I can get to solution in 32 moves. How many moves is the other solution, if you care to count?

Okay here's a little more help.

So maneuver the angle blocks to the first picture so you can get the purple 1x3 out of the bottom and into position in the second picture. Then swap the green and purple 1x3s so it's like the third picture. At this point reverse the earlier steps to get the green 1x3 into the bottom area. Then just maneuver the angle blocks to the final position.

I can't tell you how I got here, but I can show the end result. I was working on it for the longest time and finally got it.
