Depends on colors for lowers. Black lowers looks ok on dark bikes, and white lowers look ok on light bikes. Same color lowers are my preference. Extended bags look ok on RKs with custom wheels (non spoke).

I think it will look like you got a good deal on used bags and lowers and are saving up money for paint. Unless you tie in the contrasting color somehow to existing color on bike. Jim

Johnny Cash would approve if parts were from different years.
