Can the JBL 2206 or 2204 be recone with the 2203 cones?

I would like to build a small home studio cabinet with 2x2203. I believe this model can offer very deep bass in a very small volume (2 cu-ft- 57L).
I would like to compliment this dual 2203 with a single 2" 2450 for the mid and high frequency. any advice on the horns that I should use for the best flat response from 500 to 18Khz.


Your help is welcome.
Thanks,
