Request VTOL New Flight mode

Hello there, my name is Rui and im a student on Engeneering.
Currently im working on my Masterś thesis, and the project is all about an autonomous VTOL in hybrid mode.

The goal would be to have an extra VTOL state that can work as the name states in hybrid mode.
If anyone is familliar with the ardupilot firmware, it would be the equivalent to Assisted fixed-wing flight mode that can be found here:

By creating this flight mode it would allow for some interisting manouvers.

Somewhat like the transition to FW state but permanent. Id love to have some guiadance on the subject and look forward to any suggestions or help. Currently I have had some attempts but nothing remarkable yet.
