No, circuit courts limit themselves to what your appellate counsel brings, and strictly limits what you can bring up by limiting the amount of time at argument to 30 minutes or less. That translates to, at most, 2 issues, and I'm sure Mr. Ulbricht can point to over 200 at this point (2255's have a page limit, and you can move for extra pages, but you are pretty much stuck filing a 2255 only once).
Further, the original appellate process only considers matters of law (was XYZ a crime) and not matters of fact (witness alleging XYZ was also convicted for stealing Ross' bitcoins), so the juiciest stuff was barred until now.
Further, the panel of circuit judges that originally affirmed things can differ markedly with the judges who'll grant the certificate of appealability and/or consider the 2255 petition.
