Pressley or Graveman while Hader IL?

Was watching a youtube video where someone on MLB Network posed the idea that there are two relievers who have been released that are former Astros that we could theoretically sign for the pen while Hader is on IL, Ryan Pressley and/or Kendall Graveman. Not saying they should specifically go after either, as I like Abreu at closer for the time being. But if not as a closer, what about out of the pen? Obviously, neither have been good this year (otherwise neither would have been DFA’d). But, could the Astros find something with them and make them useful pitchers out of the pen for us? Just curious to see what the fanbase’s opinion on this idea is.
