Should I replace Magento with Drupal for my e-commerce solution?
Having never used Magento, I'd say go with Drupal + Drupal Commerce ;-)

Check out the following articles though:

Drupal will allow you to import products with a combination of Feeds and Commerce Feeds or Commerce Migrate (the latter requiring a bit more work).

I think at the end of the day it comes down to your personal needs.  If you don't need a fully functional CMS (or CMF...make your own mind up), then better the devil you know; might as well go with Magento.

If you want a whole integrated solution, then Drupal is clearly the winner.  I'm pretty sure there are a couple of dev houses around where I am who are migrating sites from Magento to Drupal Commerce, but I've not heard of anyone doing it the other way around.

Lastly, depending on the complexity of your project you may have to get your hands dirty with Drupal too, but it's not that hard :).
