Should MiG have used the "Faithless" design rather than the MiG-23?

We all know the MiG-23 was developed to be mass produced and cheaply at it too, and to replace the MiG-21. However as it turns out, even though it was cheap to make and produce, maintaining it was expensive (swing wing) to the point that future upgrades were not too viable due to maintenance costs and other issues.. Which is why the MiG-21 continues to out live the 23 in many airforces.

But how about if they had used the MiG-23-01 “Faithless” design instead. It’s simpler wing would’ve over come some of the complexity and cost issues although I’m not quite sure what other issues it’s lift “fans?” could generate, but perhaps that could’ve been replaced with room for more fuel. Would the Faithless have been the better design?
