It should work. Even with index shifting you can set the stops on the derailleur and use on 6 shifts of the shifter.

If you do this I would advise that you set it up so that the unused click slackens the wire while in the small cog, rather than pull against the stop on the large cog. In this way if you forget and try the unused shift it will slacken the wire rather than risk jamming the mechanism by trying to pull against the stop.

Nope, 6- and 7-speed have different enough spacing that you won't get the indexing to work. There's far more to it than having the right number of clicks!

6 speed cogs are spaced 5.5mm apart.
7 speed cogs are spaced 5.0mm apart.
There was a 6 speed Suntour Ultra with 5.0mm spacing, but you are unlikely to have that.
