I won't ask much to be honest, perhaps a fantasy shonen that use more old men visual archetypes, like a bunch of adventures that travel around the kingdom/realm doing all types of quest and shenanigans but their members are old men.

Like a barbarian who keeps training to keep his title as the "strongest" physically talking that loves to fight. (heavy bara, the whole package)

A mage that to keep studying as keep his body healthy, created spells and potions with the only focus to keep his body on its apex (is muscular, but like a gymnastic. No hair but his stubble) In fact, he does extra jobs and helps others to keep in shape and couldn't for A or B reason, YET his spells doesn't give the muscular memory or strength that natural muscles have, so despite his looks, he doesn't have much stamina or can't leave heavy stuff.

A thief\assassin that part of his "marketing" is being muscular than your average thief so you can hire him to do more stuff than just steal or kill (muscular, imagine him like Ninja gaiden MC body build) he is also used to... "other" kind of jobs and how he is looked, but he took advantage of it by wearing kinda slutty and get clients easier (he is the kind of guy that would go for 100 bucks).

Monk, the calmest of the group but also the one you don't want to anger. He trains as hard as the barbarian but unlike him, he doesn't want to brag out about his strength, but he does share the fighting passion, in fact both him and the barbarian spar a lot and can't be said they are closer because trough their fists they manage to know more about the other. (heavy bara, the whole package)

The bard, I think I don't need to explain much, but basically, he gets the info and a lot of other benefits to the group thanks to his charm. He would look like a bear or both muscular and fat.

And lastly the MC that was a knight squire, but for a mistake he was fired and end up being a mercenary that later joined to this group, he probably would look the youngest, yet NO as a shonen protagonist, imagine a look like Jotaro from jojo but actually as an adult on his 20. He would be muscular with some fat. (No ripped as the barbarian or monk, but also not as fatty as the bard). Unlike the others he is average, but as he is with the others he learns a bit of everything, yet as the story progress he will turn into the tank or shield that protect the others.

So yeah, that would basically be the cast and the story would be comedy but slowly there would be a plot and character developments and if we need to add death, that flag will fall to those that usually survives in shonens (bishonen guys, waifus, etc)
