For me it would be attractive as well. I believe this machine would be quite potent and nearly a 4th gen-fighter. Nevertheless it would be interesting how the selling would be done? Would it be a standalone plugin? Would it be a 'giveaway' for all those who own the AJS?
And even then, it would appear that DCS would grow into some sort of IL2, which had an immense number of the same plane - in all variants possible.
However it would add another fighter to a higher level, which is indeed good - a mirage needs some opponents i believe ;)
