OP, did you find a ride?
Both March 21-22nd have people launching at Sandwash per the calendar so there is hope there. But there are only two launches a day and only Saturday the 21st is booked out totally. I assume you are the only launch on Sunday at this point which means trying to catch that crew driving in friday for their Saturday launch.
I don't know about most folks but my crew is almost always packed to the brim for our desert floats. I love helping (most) hitch hikers when I can but its rare I have space when driving down roads like those into Sandwash. San Juan, Westwater, Ruby/Horsethief: sure thing. Deso, never have I had spare room.
The OP is best served to consider the hitchhike in five segments: Swasey's to I-70; Hwy 191 to junction with Hwy 6 (just past Helper); Hwy 191 through Indian Canyon to Duchesne; Duchesne to Myton; Myton to Sandwash. Only two of those segments are super friendly to hitchhiking, 191 to Helper area and Duchesne to Myton. Fewer people travel to Duchesne than use Hwy 6 to access cities to the west so it could be a major holdover at that junction, but a ride can likely be found within a couple hours. Myton to Sandwash could easily leave you stranded and not making it in time for your launch. Swasey's is relatively dead that time of year and could take several hours. Doubling or tripling the normal drive time would be a minimum amount of time I would use to predict the trip.
All in all....I wouldn't start hitching any later than Friday morning. You could find someone to take you all the way or grease multiple rides in the 200+ miles you are trying to link but I wouldn't put money on a quick trip. Its an epic hitch hike any time of year and more so in the shoulder season for Deso.
More power to ya if you pull it off. I hope the trip goes off without a hitch and you get to enjoy the brilliant solitude of the canyon.
