If you have the market for an HSR (a real one) it's feasible, thought not great and you'd really need better downtown public transport. Assuming direct it'd be a ~1:45 trip, possibly 1:30 on the really modern 350km/h (~220mph) lines, and if you don't have trouble falling asleep you can usually sleep/nap, you can work, and you could have a meal service.
Not cheap though, HSR tickets are not $10 (though it's not that far if you're using a high-frequency subscription thing, especially if you're using it daily).
