I'd like to build character that is based on using spells alter self and monstrous physique to gain multiple natural attacks and boost them (so forms like troglodyte and gargoyle etc.)
sorcerer/monk comes first into my mind, but that is super MAD.
Any advice?
Attempt is futile?
(edit: I tried to search with troglodyte, gargoyle, alter self and monstrous physique, but I couldn't find anything suitable)

If you can use non-core races, you might build a skinwalker. They all get some form of natural attack in their bestial form, which allows you to save your spells/extracts for self-buffs. Just don't pick a breed/subrace that nerfs your primary casting stat.

Druid gets close just with core wild shape.
But if you want more arcane:
Alchemist can do it (especially with certain archetypes).
Magus.
Spell-combat plus spellstrike with your natural attacks. Nasty. Plus you can get Hex Strike if you go Hexcrafter if you really want to add a twist to your melee attacks.
Spell-combat full attack sequence:
Declare spell-combat
Cast spell. (for shenanigans with Prehensile hair so you don't lose that "free hand")
Full attack sequence. (Popping whatever spell you cast as well.)
Swift action Hex Strike.
If the target isn't dead after that, he's probably really hurting. Granted takes a few levels before coming fully online if you decide to add Hex Strike.

I know that druid wild shape is almost what I was looking for.
Actually my idea was inspired by druid, but I was looking for something more monstrous.
Yeah, could just make a Beastmorph Alchemist. That would pretty much do exactly what you want.
You are absolutely right.
I'll just have to search for some basic "tricks" to boost natural attack damage and I am good to go.
Magus.
Spell-combat plus spellstrike with your natural attacks. Nasty. Plus you can get Hex Strike if you go Hexcrafter if you really want to add a twist to your melee attacks.
Spell-combat full attack sequence:
Declare spell-combat
Cast spell. (for shenanigans with Prehensile hair so you don't lose that "free hand")

Swift action Hex Strike.
That sounds very efficient. I have to think this option as well.
Magus concentrating on natural attacks, I didn't thought that.
