Practical metamagic requires spellcraft of 8, so you can't take it earlier than 6.
Also, MPSS requires 3rd level spells to enter.
Then reverse them with Easy metamagic. MPSS is perfectly valid where it is, thanks to Sanctum Spell, and in fact is easier to enter at 3 than at 2 (which requires one more feat)
EDIT : And I lowered the whole by 5, 3 (2 Chain, 1 Reach) from Easy/Practical Metamagic, 1 from Sanctum, 1 from Metaphysical Spellshaper's capstone. +5 total modification, -5 mitigation, back at base spell level, which in this case is 0th.
