I'm going to take the simple approach to this and see what comments we get.
If you determine clearance at the toe of the gear, it seems to me that the tool edge radius cannot be larger than that clearance. This assumes that clearance at the heel is larger than at toe. That's the simple take.
Now if the root angles are modified or offset, or if the addendum is adjusted by design, then the clearance will be modified as well. So I suspect there is no simple answer to maximum tool edge radius.
This is a very good question, so maybe someone else would like to contribute, please....
