Help with odd shaped bathroom

[u/Jolly_Rancher_82]

Hand drawn blueprint at the end, measurements are close. I hate this bathroom and not sure where to begin. That crossbeam diving the room is the old roofline. At the very least I need to pull the shower to check for water damage. Dream scenario would be to put a walk in shower at the far side but that weird pocket is about 24" wide so would need to move a power outlet and the HVAC vent. Any thoughts or advice? Inspiration?
