Route South West Of England: Bristol Parkway-exeter And Cardiff + Filton-cardiff

I want a new route named South West of England: Bristol Parkway-Exeter and Cardiff + Filton to Cardiff (very long name btw), featuring Class 800 in normal and named variants, class 221 in XC and Ex-Avanti XC (A 220 with refurbished livery and better sounds is planned to be included), + Class 165 and 158 DEMUs. It sounds cool for me to drive it if it ever came out, please! Based in 2026-Present day.
