I need to upgrade the crappy component speakers in my
car. But the crossovers lie within the front and rear
amps.

There are probably some equalizers in the system, someplace.

I really don't want to have to replace the amps.

You might have to replace the head unit, too if you want to erase all the
vestiges of your OEM car system.

The quotes I've seen thus far are about $2000 to replace
just the front speakers and amp, and a front/rear
solution $3000 or more. That's nuts.

It is all about costs and benefits.

Is it possible to connect the two wires for the tweeter
and woofer in order to regenerate the original unsplit
signal?

Anything can be done with enough money and time. In this case it seems like
futility.

I suspect this may do interesting things to
impedance, but it seems like it ought to be possible with
some fiddling (and a lot cheaper than reamping).

OEM car systems aren't necessarily simple any more.

BTW, it's a 2002 BMW 3 series coupe with the Harmon
Kardon 12 speaker abomination.

Well, in their way they tried.

However, consider the cost of the car to you. If you're a real music lover a
car with a bad stereo is a broken car.
