Converting stereo single ended to balanced mono?

Hi, I have three Thiel 3.5 stereo equalizers (bass boosters). These are single ended only. I was wondering about the benefits of trying to convert two of them to balanced mono operation. Is it possible? Is it worth it? What are the options for doing this? What are the pros and cons of these options? Are there any other upgrades that might be considered if and when these conversions might be done?

As always thanks in advance.

@unsound, have you ever considering bi-amp the cs3.5?
Thiel use parallel crossover design can easily modified to bi-ampable, so the bass equalizer will has no effect on higher frequencies.

IMO, it will benefit if the rest of your system is true balanced.
make one stereo single ended box do the two positive parts (both R & L positive. (and then you are actually doing NOTHING to the internals of the box!) .. and the second box do the two negative parts. Again, once you have the negative signal, you are just entering it into a not modified box.
