Sure thing.

After the Quincies come back and their leader, Yhwach, kills Yamamoto, Ichigo learns that the being whom he believed was Zangetsu is actually the manifestation of his Quincy powers (inherited from his mother, a pure-blooded Quincy) and also finds out that the being we knew as Hollow Ichigo was the real Zangetsu all along, having being a regular inner Hollow also inherited from his mother that fused with his Shinigami powers and became active once Ichigo went to Soul Society. With this knowledge, Ichigo had his Zanpakuto personally reforged by Ouetsu Nimaiya. Turns out, the true Zangetsu has two blades, each representing a different aspect of his powers (Hollow&Zanpakuto!Zangetsu & Quincy!Zangetsu).

As such, the inner Hollow is still present, and as such it is likely that Ichigo can still don his Hollow mask, but given that he now has access to the full power of his Zanpakuto - which his Hollow powers are part of - there may not be a reason for him to do so.
