Hey there, I absolutely love the look of this conversion. May I ask how you managed to get it looking so much like an actual paizo product?
It's really great to see that people are still working to recreate some of my 3.5 favorites like the beguiler. While looking this over I was struck with a little inspiration myself. I think you may have a decent framework to build a factotum look alike as a beguiler archetype. Give it more skills/level, an inspiration pool like an investigator, let it use savy preparation for a wider stable of spells and swap order powers out for the factotum's other class feature mimicing abilities. Just though5 I'd drop the suggestion incase you liked it.
