@JeanBaro_ yes this is doable, but honestly you want to keep this process out of AEP (or any cdp), quite a few reasons for this, some of them include
- The data from the web forms ideally should not include PII ( from leads) if done via client side, you can explore doing this server side but would require quite a bit of tech design and build
- Consent & Privacy: You may have to adhere to any privacy and data regulations based on what data you collect and get consent on each platform
- Data Anomalies & Updates: Data imported into AEP may not always be correct or right format, any changes at bulk, including wrong data in profile will take enormous effort to update/delet and will include help of adobe support & may be additional cost
