To start off, let me say that Sasori most likely won't approach the Nidaime Mizukage in Hiruko due to one reason. It would be foolish to approach a Kage in a Hitokugutsu such as Hiruko, and Sasori likes to make sure that he is safe inside of a battle. Because of that one reason and Sasori being the type of a guy that likes to make sure that he isn't in danger, he surely won't approach the Nidaime Mizukage in Hiruko.
Even if he does start out in Hiruko, it doesn't really matter that much since the only way the Mizukage has of breaking Hiruko is Jōki Bōi. The explosion would surely break Hiruko [

], but that doesn't mean that it would kill Sasori as well. As we know, Chiyo needed to use Sakura's strenght to break Sasori's Puppet Armor; Hiruko. [

Now please do remember that Chiyo has a jutsu in her arsenal that could easily crush Puppets. [

Alright, since Chiyo didn't have anything that can crush Hiruko in her arsenal despite having a technique such as the Sanbō Kyūkai [

], she had to use Sakura's strenght to crush it. Do I need to remind you how strong Sakura is? She was able to smash a giant boulder without much effort put into it. [

Even with her strenght, when she smashed Hiruko, Sasori himself didn't recieve any damage at all. [

] This means that if Jōki Bōi explodes and breaks Hiruko, the puppet itself will tank a portion of the explosion while Sasori's body will tank the rest. How exactly? Well, to make things worse for the Mizukage, Sasori's body is actually a better defense than Hiruko is. Unlike when Hiruko, Sasori's real body didn't shatter when Sakura punched him, it simply reconnected. [

Now before we come to a conclusion, let's look at Jōki Bōi's explosion for a moment. [

Since we can easily compare the Jōki Bōi's explosion to the Shī Tsū explosion which was tanked by Sasuke, Sasori's body should be capable of tanking the Jōki Bōi's explosion. Especially since Hiruko will tank a portion of the explosion before it hits Sasori himself. As long as Sasori guards his core, it doesn't matter. His body feels no pain and he will just reconnect back if the explosion blows away his body parts. [

Well, it only makes things easier if Sasori decides to start out with the Sandaime Kazekage instead due to the Satetsu. [

] Unlike Gaara's normal sand, which is considered to be the absolute defense [

], Satetsu is a better defense due to the original material that it's made out is iron. Since Gaara's normal sand was able to tank a Jōki Bōi's explosion, Satetsu would tank it as well. [

To fully counter or avoid Jōki Bōi, Sasori has two options:
1) Since it has been stated in the manga that Sasori can create any shape out of the Satetsu, he can simply make something that would help him to fly off. [

] Basically he can make the Sandaime Kazekage grow Satetsu Wings [

] and then he can simply make a Satetsu Block or hell perhaps even a Satetsu Bird that he could fly on. Because of that, the Jōki Bōi now has no way of reaching Sasori.
2) He can simply keep an amount of Satetsu at his side and everytime the Jōki Bōi explodes, Sasori can make the Satetsu mix with the hail produced from the explosion. [

] Eventually, Sasori can just envelope the Jōki Bōi clone in the Satetsu that is mixed with the hail and then it won't explode again. [

] To catch the Jōki Bōi clone with the Satetsu won't be really hard since Satetsu is extremely fast [

] Let's not forget that Sasori can use his flamethrowers to make the Jōki Bōi explode before the Mizukage plans to set it off. [

] Someone as intelligent as Sasori will figure out how to stop the Jōki Bōi sooner or later.
The Nidaime Mizukage's clam summoning won't really be a threat here as well since it only uses Genjutsu via a mist. [

] Sasori can simply fly out of that mist on his Satetsu, but it doesn't really matter since Sasori is a Puppet so Genjutsu doesn't work on him. [

The Mizudeppō no Jutsu isn't a threat here at all. Everything Sasori has can tank it. (Hiruko, his real body, Satetsu)
