You’re thinking of neofascism as a compound form of neoliberalism there, which I think is a mistake.
The people migrating from US-style neolib views into protofascist veneration for a strongman aren’t stacking one thing on top of the other. They are breaking with a neoliberal scheme that didn’t do much for them and into a fascist mindset that presents itself as revolutionary.
Had the left done a better job of channeling that disaffection they could have broken leftwards. They didn’t, so they abandoned neoliberal views for neofascist ones.
I am very skeptical that the conversion path for those fascists is back to neoliberalism and then from there to a more leftist stance. The left isn’t competing for the people already radicalized right, they are competing for the people that keep shedding off the husk of the liberal establishment.
And they’re losing.
We have distinctly different ideas on how this works. Both hypotheses are untestable, though (at least to us).
Or, you know, to put it differently, “agree to disagree”.
