 |  "Complex bath exhaust challenge in older house"

We have a 60's brick ranch house that we are remodeling ... one story with a full basement ... it has 2 small baths that stack on top of each other, both on the back wall of the house ... the exterior wall on the top bath is brick veneer on wood frame and the the exterior wall on the lower bath is 10" concrete block ... now, the issue we have ...
neither bath has an exhaust fan ... I don't want to just exhaust the upper bath into the attic space and going through the brick wall to the outside would be a pain; however, going into the attic and piping to the soffit (we have a fairly wide overhang) seems like a reasonable solution ... but, what about ...
the lower bath? ... the only options I can come up with to vent to the outside is to go through the concrete block exterior wall (ugh!), go into the space between the two floors and then through the brick exterior wall above (not easy either), or lastly ...
go up and through the upstairs bath and tie into the exhaust pipe in the attic (in other words, share the same exit pipe with the upstairs bath) ... this could be done fairly easily since both baths are currently torn down to the studs ... my question is ...
can or should this be done? ... I've never seen it done before ... it's a long way for the exhaust to go up and out from the lower bath to the soffit on the upper floor ...
any ideas or suggestions about how to solve this exhaust challenge? ...
if my idea makes sense, how should I size each of the exhaust fans? again, both baths are small (about 7' x 7').
Thanks in advance, Bill

I would use 80CFM or larger and tee them together.
Broan make some really quiet models capable of this job.
