It's a nice thought, but not really likely. Ross Ulbricht didn't have access to the closed cypherpunks community that Satoshi first delivered his idea to...it was a group of 8 people or so, really tight. Nor does Ross have any background or experience in the technology needed to create a digital currency.

Have you seen the documentary Banking on Bitcoin yet?

Near the end they make a really logical argument for who may be Satoshi Nakamoto, focusing in on two people.

(1) Nick Szabo, founder of Bit Gold Proposal: It turns out the Bitcoin is nearly an exact copy of a previously released but failed version of a digital currency called Bit Gold. The gent who created Bit Gold, Nick Szabo, was part of the original 8 cypherpunks to receive the Satoshi's white paper. Given how closely Bitcoin resembles Bit Gold, many people believe Nick Szabo is Satoshi.

(2) Hal Finney, the first person to mine and transact Bitcoin with Satoshi: Hal was part of the cypherpunks group that received the white paper. Hal also lived within 2 miles of Dorian Satoshi Nakamoto, the California resident that was once falsely "accused" of being Satoshi. Some time after Bitcoin went live Hal was diagnosed with ALS (Lou Gehrig's Disease) and sadly he passed away in 2014. The escalation of Hal's disease (when he would become more incapacitated) is said to align with the time that Satoshi went dark on this forum and other communication channels with core developers.

We do? How? Because Hal convincingly told a reporter for Wired that he wasn't Satoshi? Lying isn't as difficult as you think, especially when it's for the right reasons.

The reasons for Ross' arrest was logical and legitimate for his involvement in Silk Road, to presume that this logical and legitimate reason is actually a farce to cover another reason (i.e., he's Satoshi) is textbook conspiracy theory thinking. You're looking for connections that don't exist. The weak part of this argument is that your connections you're trying to make aren't as plausible as reality.
