It would be cool to go with the "core 4" if someone wants to make a wizard and a rogue.
I think one of the letdowns about Vecna is they don't have a 9th level spell. It just seems weird to call him the master of magic when your PC wizard is packing better spells than an Archlich.
foresight or timestop are good candidates for "time travel" abilities.
Or....one idea is to give him Wish, but specifically note he only uses it to replicate 8th level spells. This maintains the 8th level slot powerlevel, but gives Vecna incredible flexibility, allowing him to tailor himself to any party that comes against him. This means as long as Vecna has any knowledge of whose coming at him....he will ALWAYS have something to bring to the table, no matter the combo. That to me seems a perfect way to ensure Vecna is never just tripped up by a specialized party combo.
