This was my route at the time. It was a massive slog, especially on the Boxercup I had at the time (but very fun up the Susten).
I wouldn't do this today (you basically never stop) but you can cross through Switzerland (motorway) and then jump on a few of the classic passes of the rollercoaster, not all if you wanna do in one day.
If anything can be avoided, I'd say the Gotthardpass is the least interesting of the bunch, by far, in all honesty.

Remember: Switzerland and Italy motorways = green. A/National roads = blue.
