My 2 cents:
First unit will not draw 80. That's just the max OCP. Same with second unit. I would size 50 and 30, plus the electric heat. They may run concurrently from time to time, but not for long periods.
If it is still an issue, you can add a control to lockout the geo unit when the electric heat is on, but the electric may run a little longer then.
