This is what I'd do.....
-Get a PPL based on your foreign licence
-Add the IR "us test passed"
-Add the private ME with IR "us test passed" (then all ME hours are PIC)
-Train for CPL ME (all hours PIC, inc. required cross countries)
-Take the CPL flight test in a Multi first, requires 10 hrs of PIC in mulit's which you now have. Doing ME first negates having to do the SE CPL in a complex aeroplane so you can train in a cheap 172. Also you meet all x/c requirements of SE CPL. You are already IR'd, you already have the CPL ME so the flight test is a straight forward vfr manoeuvre test with no navigation as that has been covered in the ME test.
-Take the CPL SE in a cheap C172
(the above is what I did)
-Do the CFII rating as initial FI rating with FAA inspector
-Do the CFI rating with DPE
-Do the MEI rating with DPE
Good luck!
