Obviously it depends on the year and the entry point, but I find the comments about Death Hollow being too cold in early April should have an asterisk. In 2021 I hiked solo from the Boulder Airfield via the Boulder Mail Trail to Death Hollow and then out the Escalante River to Rte 12 on April 2-3.
The water was relatively high but never over my waist, I was in the river almost as much as I was out of it, and found the water temps to be quite tolerable in only a single pair of Prana Zion pants and approach shoes for this former New Hampshirite. Unfortunately for the original poster, it only took me a moderate day and a half to complete, but you could always do some side canyons to extend it. On the plus side there was no one else on the entire trail and the notorious poison ivy bushes were dormant and easy to avoid.
The one troublesome spot for me was in navigating the Narrows, where the traverse ledge was under water and covered in long strands of algae. Despite my previous 45 years climbing experience (including USA Climbing Regional Coordinator), I ended up in the drink. It was only a 10 second float from entry to the beached whale mantle at the end, but I got drenched; fortunately the contents of my pack stayed dry. If I had to do that again, I’d bring a cheap toy inner tube and parachute cord to float the pack and my clothes so I could swim it outright and have dry clothes to change into after.

About to drop in to Death Hollow.

Lower Death Hollow.
Last year I was planning on hiking the Woodenshoe-Peavine Loop, but after researching it I found the reports of endless sections of hiking on beach sand, ample quantities of horse pucks, and the relatively small walls and wide open nature of that section of canyon to be off putting. I think the section heading west from Woodenshoe would be more interesting and more suitable for your time frame, but you would need to arrange for a shuttle.
I ended up changing my plans to hiking a loop in Bears Ears along Point Lookout Canyon (AKA East Slickhorn) to the San Juan River then back to my truck via Slickhorn Canyon. About 2.5 days.
