Is it a good idea o use the link on the logo to display a sup-header with navigation options?

My website has two different section, one where we do real-time comparison of international money transfer costs, the other where we review different money transfer operators and banks.

We have "two homepages", one for the comparison vertical, one for the review vertical. At the moment, a click on our logo redirect to the "Comparison Homepage", which historically has been our main homepage, but it confuses a lot our users who first landed on the "Review Landing Page" and who cannot find the homepage they first arrived on.

A solution to this problem would be to display a sup-header when a user click on the logo, offering direct access to both services (comparison & review), and a link to both homepages.

I think it would work quite well (currently testing it with users), but I am not sure yet it is a good idea to "hijack" the standard comportement a user may expect when clicking on the logo.

Does someone have experience with that or any insights to share ?
