Shimano 8 Speed Indexing: Will This Work?

I'm curious if this will index. I'm going to install the Shimano 8sp bar end shifters (thanks, Brock!) regardless because if it doesn't index to my satisfaction I'll just use the friction setting. But here's what I have.

Shimano 8sp bar end shifters
Shimano 8sp HG cassette
Shimano 130mm freehub
Shimano RD-MT60 long cage deraileur (ca. 1988; meant to index with 6sp shifters)

I suppose at the heart of the matter is this: Is the design of the MT60 similar enough to a modern 8sp compatible RD that the cable pull from the 8sp shifters will place it in the right spot over each cog?

The spacing on a 6sp freewheel is something like 5.5mm and is 4.8mm on an 8sp, but all that is related to the pull of the shifter itself, correct?
