After looking over their program schedule I would IMO see little to no chance of this happening, at least on 57.
Reason I say this is because they broadcast most of the same programs as 51 & 55 already show. Judge Hatchett, Judge Karen, Hawaii 5-0, Brady Bunch (I believe 51 owns the rights to show), Frasier, Quincy, Matlock (use to show on 55). The only shows I see they do have not currently being shown here are Perry Mason, Andy Griffith and Twilight Zone.
Not to mention their weekend lineup is even more watered down than 51, if that's possible. Their lineup starts at 7p? Huh.
I would welcome something of this nature or RTN to 57 with open arms but I won't hold my breath.
