AB probably already have the equivalent software to provide a Pseudo Air Speed (PAS). The software will provide PAS in every a/c configuration, but like everything else in FBW systems it too needs some external references such as air pressure, OAT and altitude. The a/c configuration clean/unclean, CG, weight, thrust, AoA, pitch, bank angle, spoilers, slats and gear etc., down to and including ground effect should provide a IAS/TAS equivalent to that provided to the ADIRUs from correctly operating Pitots.
Lets face it, the SIM algorithms operate using the same principle.
