Question regarding smart thermostat

I have a three-story house, which was set on a single zone for heating-cooling. So, the usual problem: upstairs bedrooms are warmer than the basement. The HVAC system is 17-years old, so I think it will be up for replacement in a couple of years. Two questions:
Is it financially feasible to change it to 3-zones when I replace it?
Until then, if I use a smart thermostat with a temperature sensor placed upstairs, would that be a substitute?

Most homes were set up for hot air heating and A/C was added later. This type of system will only ever be marginal for A/C. With a heating system.... the registers and the returns are low. For optimal A/C operation the returns and registers need to be high.

1) Multizone forced air systems is home are typically marginal in operation. Very hard to get proper balance.
You would be better off having two separate system.... first and second floor. Get multiple quotes and system ideas.

2) Thermostat with remote sensors won't help your problem. See the following thread:
