To answer "is the Digital HVAC swapable". Most reasonable answer is no. Heres why;

If your FRS comes with manually controlled climate control, chances are it lacks the hardware (control arms, etc..)to operate the vents automatically used in the Digital Climate control. Vise versa, Digital HVAC controls lack the manual control arms to operate the ventilation in a manual climate control.

Because of this control mechanism, the size difference between DHVAC & Manual Climate is likely substantial, and the wiring will likely be different by a few pin differences if any.

I think you are wrongly assuming that manual=mechanical and that only automatic climate controls are electronically controlled. It appears to me that the manual HVAC controls operate the blower and ducts electronically rather than mechanically. The giveaway is that recirculation is controlled via a button rather than a big slidey knob. I'd say it's quite possible that the only difference between the auto and manual HVAC is the controls. Given that both are electronic, it wouldn't make much sense to have different blowers, ducts, or wiring harnesses.
