I wonder how feasible it is for Sony to revise the Neo hardware to something more powerful considering MS's moves and that the HDD on the current consoles are actually PC parts with minimum customization
I don't think (believe) Sony cares if Scorpio is more capable than Neo in raw output. Sony goal is to get Neo out this year, along with PSVR, and grow it's current PS4 userbase. If, Sony does offer some type of forward hardware upgrade port within Neo, then that maybe the way to go. But as of now, Sony main goal is to get them (Neo/PSVR) out the door this holiday season.
