If you combine the FPV and attitude, then technically yes. However, you will also need to know what reference the attitude is taken from (one would assume the body angle) and compare this with the angel of incidence. So it's a bit complex.
Several accident reports have mentioned that an angle of attack indication would have been useful to the unfortunate crew and I gather it is an option on the A320 family. But no customer seems to fit it. I have flown aircraft with AoA gauges (all military) and they are very useful.
