I am pretty sure this would cause pretty large issues. You should separate both systems entirely, with no overlapping CT's.
There may be ways to make it work if you really wanted to., the much better solution imo is an automatic or manual transfer switch to backup both sides of the service from the same system.
I am probably not being very clear in my description of what my installer is designing. It is what you are describing. In the final stages now, but install won't start until the last week of February.
