Yes and no.
It would've been better for DmC if they pitched it as a canon entry than a reboot. Letting it be another sidestory/prequel etc.
Before DMC5, DMC stories was pretty disconnected from each other. There are recurring elements but the stories were self-contained.
So it could've been another case Dante took offscreen. Most of the games take place years apart so I assumed he did other cases. DMC3 is set 10 years before DMC1. So just put it there.
You might have to change a few things like Dante's half angel status and Vergil/Mundus's roles but it's not insurmountable.
If anything you could've made it a new character wholesale and do that. Just set it in the DMC version of Britain and go from there.
I loved V and I like "V is not part of Vergil" fanfiction. So giving him a spinoff before he pops up in 5 would've been cool.
