i cant come up with a better concept that dosn't ad significant weight to the carriage. I was thinking about a quick release on one of the hot ends, but i think that would still require re-alignment each time.
the only alterative i can think of is that Micron (3dp) has a dual extruder design where the head and barrel unscrew from the heatsink and heater, and they give you spares.... that might not be so bad, jsut unscrew the unused one and you get an extra few mm of clearance. they make use of nema 11 geared steppers, allowing them to keep the heads closerr to each other. .. i they are geared on the high side... and a bit costly like 400 bucks or something. looks like they resolved the flexable filament issue with a new extruder design called cobra
I'm not a big fan of micron / 3dp though due to some recent misleading practices, and the fact that they still sell thier older flawed extruder.. i simply don't trust them.
