You could go for as many theories as you like, provided that the theories you end up employing to flesh up your framework do not contradict each other. In my MA thesis I used Conceptual Integration Theory (CIT), Distributed, Emergent Cultural Cognition (DECC), Cultural Discourse Analysis (CuDA) and Corpus-Assisted Discourse Studies (CADS) for my framework on Corpus-assisted Discourse Analysis of Cultural Cognition.

Thank you Asterios Chardalias for your answer

Dear Mr. Bakari,

Belief in theory liberates thinking, belief in a theory confines it. However, a word of caution deems necessary here. In scholarly tradition, it has been maintained that the major role of research design is to consolidate the different parts of the inquiry in a logical and coherent fashion to tackle the research problem. It constitutes the plan for the measurement, analysis, and collection of data. Clearly, research problem determines the type of theoretical framework, implying that also in this sense, inquiry is problem-centric.

Best regards,
