Your solutions work OK - thanks to both of you!
But I have a question (maybe I should have written this before):
What I must change is:
....MMMMiiii => ooooMMMMiiii
....MMMMoooo => iiiiMMMMoooo
iiiiMMMM.... => iiiiMMMMoooo
ooooMMMM.... => ooooMMMMiiii

I mean, If you do not have some character before the '.' , how will it understand to replace for example, '.' with 'I' if I have 'O' after the string of 'M'? Is there any chance that this can be done?
