Hiking the TCT (backwards)

We are going to hike the TCT in May. Reservations are set! How hard is Silver Peak going in the opposite direction (towards Avalon)? We plan to Spend the night in Two Harbors at the Banning hotel our very first night on the island. The next morning (day 1 of our hike) we will hike around Silver Peak on the coast road to Parsons. We will set up camp, and then we will day hike to the Terminus at SLB. SLB to PL (night #1); PL to LH (night #2); LH to BJ (night #3); last day hike ALL the way to Avalon. My husband is a purist, and wants to hike the trail from end-to-end without deviation if at all possible. Is this a bad idea? Also, how safe is our stuff at Parsons? Can we rent a locker to secure it while we are on our day hike to SLB?
