+1 on the roof cut. Re-scalped a Civic w/o welds a while back....not from collision damage but by stubborn rust. Honda used the wrong sealant on PhDM units of that era. The JDM roof had 0 corrosion & got the proper scalp-frame adhesive.
Your pillars, repaired or transplanted, must be carefully aligned relative to doors & windshields. This will be skill-dependent. Look for a good builder.
