Anyone ever upgrade a pair of RT2000's?

A pair of RT2000's (in fact, my originally owned and previously sold pair) fell back into my lap yesterday. I like their sound but they do lack in the mid range department where their older siblings (RT3000's) deliver. I contribute this to the fact that the 3000's have the additional 6.5" midrange driver and Polk does some tricky x-over stuff with that configuration.

I got to looking at my RT800's which I recently purchased and realized that I essentially have the 1 tweeter, 2 mid-range driver configuration there.

What I'm wondering is whether or not I can DIY an upgrade to the RT2000's and essentially replace the 1 tweeter, 1 mid-driver upper section with the 1 tweeter, 2 mid-driver part from the RT800's and acheive a better sound.

Thoughts?

    Are cabinet dimensions the same? You will obviously need different crossovers... Maybe try RT800 crossovers, but then you will have to figure out how to hook up the subwoofers - hook them up via separate LFE and make them completely separate from the upper section might be the easiest way.
    I haven't seen the RT800 crossover, but you will have to figure out how to hook up 2 mid drivers instead of 1. Hooking them up in series will give you higher impedance (if I remember, they are 4 Ohm drivers, so you will have 8 Ohms)... if you hook them up in parallel, you'll get 2 Ohms... Something to think about.
