whats wrong with the two existing t-stats? set them both for the
exact same temp and leave things alone. either they'll reach set
point or they wont.
the first priority is determining if the system is capable of
auto-changeover, if not, installing the required components to make it
so. (usually t-stats alone will do it)

for the life of me I couldnt find in the original post where he
describes a 2 story house. maybe its a rancher on one floor.
at any rate, we have no input on duct sizing, system capacity or zone
duct sizing or capacity.
If its 2 story, I'd set the first floor stat a few degrees COOLER in
ac mode and a few degrees WARMER in heat mode. Cooler because that
zone will satisfy first, allowing for a much longer run time for the
upstairs zone (if any).
