Adhering to project-switch-commands might be a fine idea, indeed. 
Although I'd probably prefer to just use Dired, myself.

Semantically, just going by the command's name, it seems to me that

finding a corresponding file - a secondary one.

Perhaps we'll want to add a command called 'vc-worktree-find-matching-file'?
