The Inner Hollow seems to get along well enough with Zangetsu. They'd all just be incarnations of the same thing, after all: Ichigo's power. It'd just be that they're different aspects of his power.
At most they'd squabble a bit, and eventually the Inner Hollow absorbs the other two as his power increases, like he did to Zangetsu in canon. Not that that'd stop Ichigo from calling on the Angel, but it'd also make it very risky to do so (like how using Bankai resulted in him going hollow until he beat down the Inner Hollow and got the mask).
