Just checking on older posts and saw this.
I really dig Lancers, so I sure hope you either leave it as-is or carry it through to completion.
I've seen a couple chopped and in both cases, they had a "Gentleman's Chop" which is a very minor one.
This was also done on the 50s Studebaker coupes.
The rear of the roof was left in place with a slice from the front to back at the top of the "C" pillar. Then the front pillars were cut about an inch to 1 3/4" and the roof 'leaned' forward and rewelded lower in front.

A new chopped one I found. This also has more out in front than in the rear, but is more than most of these chops. It sure looks like all the glass is now lexan...
