I think that's a good idea. I'd like that myself, and it's more reasonable now that there are controls for friendly fire and collision with friendlies. I will consider adding it as an enable/disable option in v5.0. Klonan had his troop units use this style of shooting for this Total Automization mod, but he changed it back to instant-hit shooting for most of the units, to make them more consistent/useful... from what I remember.
