I'm actually afraid an anime series of X will be as poorly written and unfocused as the series itself. Also redundant.
The only sagas that might be good in an X anime is the beginning (X1) and the Repliforce saga. After that, it'll sort of end (reach its peak), only to keep going and stagnate quickly. But by then it'll have already set up for a Mega Man Zero anime, so nobody but X fans will give a [parasitic bomb].
On the other hand, it could be unusually well-written and revised, like the Archie comics are now for Mega Man.
Actually, I'd totally like to see a Mega Man Archie show first.
