[Star Trek] [Star Wars] If the Borg were to assimilate Darth Vader would he still have access to the force? If so would the collective become force-sensitive?

That depends on the nature of the crossover. If the Force exists by default, then there's no reason why the collective couldn't have discovered and mastered it, even without Darth Vader. 

If somehow the collective had no access to the Force or for some reason none of the assimilated were sensitive to it before, then it would be sort of Dark Nest sort of situation - while assimilated, one drone (Darth Vader), has his powers massively augmented by collective will of the Borg, giving him additional power to act for the Collective in ways that were closed to them before.
