I vaguely recall your original post and it all still applies, pretty sure I covered all the pros and cons in some detail.
It can depend on the bellbox, but if it has no special multiple box connections then you would just series them. I don't see where you feel it would be an issue.
Wiring a bell to a zone would normally require you to have tamper lead you can separate from the PCB for it to operate correctly, this removes some of the self activating feature of the bell.
If it where a new installation now with Texe I'd just use an expander input for additional bell tampers keeping them separate, but everyone's kits different as above.
