Cloud pages internal notification to different email addresses based on form data

Hello All: I have a smart capture form in a landing page and want to notify email address 1 if Radio button 1 is selected or email address 2 if Radio button 2 is selected on form submission.

Current impelementation:

1. Added a hidden attribute "SubscriberKey" on the form that has an email address attached to it in the "All subscribers" list
2. Form pushes data to a sendable DE
3. Journey is checking for DE rows in point 2 and triggering an email activity to the subscriberkey's email

Can any of you please guide me on the approach/ solution to route the emails to different addresses based on form data? Thanks in advance
