Could i use a drawer within an overlay modal?

I'm prototyping a candidate selection application for a job agency. The client needs a module in which they can filter to search for the right candidates for a job. When they click on a candidate in the list, an overlay modal pops up with all details on that candidate (there are a lot) + an action module in which an agent can call or mail the candidate in real time and track what's been discussed. The modal already displays a lot, but the client also wants to display the history of that candidate, useful as context when calling the candidate. I would like to display the history's information right into the modal itself but it's too crammed with other info as it is and an agent won't need it all the time. I was thinking of displaying this info through a drawer within the modal but it feels like cramming too many patterns into one functionality. I can design it as an accordeon pattern but that's basically the same behaviour (info sliding open)

The other option would be when the agent clicks on a candidate from the list, instead of having an overlay modal, the agent would drill down to another page. But an overlay modal feels better since you focus the agents' attention to the task.

I was looking up info on the subject but can't seem to find a lot. What is your opinion?

Thanks
