can Decimate() blend instead drop duplicates?

[dinstun]

I've read the documentation for the Decimate() function of the Decomb plugin but cannot find a way to perform inverse telecine on NTSC without dropping similar (but not identical) frames.

For a sequence of 5 frames I would like to decimate to 4 frames by blending the two which are most similar, leaving the other 3 untouched.

Yes it can:

Decimate(mode=3)

Read the reference manual to understand the relevant threshold.

I'm sorry, but after studying the manual some more and looking at the code, I still can't see a way to do want I would like to do.
For Decimate(mode=3), each 5 frame sequence is designated as film or video depending on hints from Telecide or metric>threshold.
But if the determination is "film", the most similar frame is dropped. If "video", frames 0 and 4 from the sequence pass through to destination's sequence 0 and 3, frames 1 and 2 are blended to destination 1, and frames 2 and 3 are blended to destination 2 (is this correct?).

What I'm hoping to be able to do is (blindly, not depending on film or video) blend the 2 most similar adjacent frames from the 5 frames and pass the other 3 frames untouched.

Am I missing something?

Ideally, I think an additional option, something such as blend=true would be nice. If true, whenever a frame were to dropped, it's similar neighbor would be blended with it.
My reasons for wanting this would be 1- no information would be permantly lost, 2- it might clean up some noise from noisy captures.
