Tiltshift Plugin for AE, Final cut & Motion

I'm trying to create a plugin effect Tiltshift "with FxFactory to use in Aftter Effects and Final cut. The filter is quite close to the result I want. but I do not tweak the lens blur Fx characteristic of Tiltshift. There are many tutorials for this FX in PS or AE, but are based on a combination of filters and layers to get the result. Examples: http://www.tuaw.com/2008/10/07/how-to-use-photoshops-lens-blur-tool-for-... or http://luipermom.wordpress.com/2008/12/29/tutorial-tilt-shift-con-photos... (in Spanish

My intention is to create a plugin all in one. Launch the plug and go. My first test was using Gaussian Blur, worse today and made a change by Box Blur and gives much better results. But I think it would be much more successful getting a lens blur fx. Here is a demo of my plugin running in AE: I searched but did not and managed to find an appropriate combination using NI blurs, or VADE blur plugins.

my question is, how I can create a filter with the properties of lens blur?
