The Ju 188 and Do 217 helped from the backbone of the Luftwaffe's bomber forces from mid 1943 onward, seeing extensive service in a variety of roles, with the Do 217 being notable as the platform for the first combat use of a guided munition.
And the He 177 would be an interesting aircraft to have, perhaps being perk worthy depending on the variant and loadouts given. It would also be interesting as a snapshot of German aircraft development and design philosophy, if not a particularly significant aircraft.
All wound be quite useful in the MA though, with the Ju 188, and the Do 217 being useful for certain scenarios and special events as well.
I would imagine that the He 177 would supplant a significant portion of other heavies in the tactical base attack, and potentially mediums for CV killing. It would offer something of a mix between the B-24 and the Lancaster, in terms of defensive firepower and bomb load, but would be significantly faster, though likely the most fragile of the three.
And the Ju 188 and Do 217 would potentially both be staples of the medium bombers. Both would be quite fast, with decent bomb load (though the Ju 188 suffers the same weakness as the Ju 88 in that it's internal load is limited to 50kg bombs).
