Putting a wordpress site on top of backend CMS (drupal)

Hi,

This is probably going to not make much sense as I’m completely new to this but I’ll try my best (sorry in advance).

An online company that I’m selling products for built me a website (they do this for you as an incentive to sell their product) which is built in Drupal and has a really basic looking front end and (appearance) and isn’t really the look I’m after. So they basically set up a CMS for me to use and does all this awesome reporting stuff and automatically sends out confirmation of payment emails to customers etc which is great and im pretty sure i legally have to use that system anyway. But to improve the appearance I’d love to build a wordpress site and overlay it on top of the existing Drupal site they’ve set up? Is this possible?

Really hope this makes sense and appreciate any feedback at all! Thank you ??
