Oh, here's a more complex analysis of who can craft what when (assuming my change to the levels that are skipped):
Level 6: MC and Wizard both can make items that require 3th-level spells, both can meet CL 6 requirements.
Level 7: Wizard can make items that require 4th-level spells but can only meet CL 7 requirements, MC has an extra feat, can make items that require 3rd-level spells, and can meet CL 8 requirements
Level 8: Wizard can make items that require 4th-level spells but can only meet CL 8 requirements, MC has an extra feat, can make items that require 3rd-level spells, and can meet CL 9 requirements
Level 9: Wizard can make items that require 5th-level spells but can only meet CL 9 requirements, MC has two extra feats, can make items that require 4rd-level spells, and can meet CL 11 requirements.
Level 10: Wizard can make items that require 5th-level spells but can only meet CL 10 requirements, MC has one extra feat, can make items that require 4rd-level spells, can emulate anything else in existence, including psionics, and can meet CL 13 requirements.
