That should work fine.
I-10 to I-17 to I-10 is normally pretty easy through Phoenix from 9:30 to 2:30.
Another alternative is I-10 to 99th Ave, south to Buckeye Rd, east to 91st Ave, south to Baseline Rd, east to 51st Ave, south to Beltline Rd which loops south of Phoenix/Ahwatukee and comes out as Riggs Rd at I-10 south of Phoenix. Not much traffic, but a few sections of 35mph zones. You can also exit I-10 at 51st Ave, but there is more traffic.
