I have used an FA50/1.4 on an MX, but was very glad for the split prism and microprism collar and I don't know what the F is like in comparison.
OP, the A 1.7 probably is the best compromise but it depends on what shape the aperture ring is in. Those things do have a reputation for suffering with age on this particular lens. On the DSLR it's not an issue; park it in A and leave it there. But shared with the K1000 it's going to be getting a workout. Is the copy you have available up to that?
My first impulse is to say: keep the M28/3.5 on the K1000 and the 18-135 on the DSLR. I recently did two days in Toronto with an S1a and an M42 28/35/55mm kit, and although Toronto isn't Ottawa I'd pick the 28/3.5 as first choice any day if I were going there. However, there were times I felt the want for a 24mm Takumar lens, and if one had been available in the camera stores I visited, I would probably have bought it. So if your Sigma 24mm is a film-era manual-focus full-frame lens, I'd bring that along for the film camera instead of the 28/3.5.
The 18mm end of the 18-135 has the same field of view as a 27-28mm lens on full frame, and is the widest option you describe for the DSLR. You'll want that at times. Leave it on during daylight hours. Save the 50mm primes for sunset and after dark.
If you're shooting as a team, leave the A135/2.8 home unless he really, really wants to take himself off somewhere else and feels the need for a tele lens on the film body.
