This is not an answer, but, based on chuy's solution, I want to show someone of the advantages of the new V10 Inactive:

(x = Inner[Inactive[Times], {{1, 2}, {3, 4}}, {{5, 6}, {7, 8}}, Inactive[Plus]]) // MatrixForm

Activate[x, Times] // MatrixForm 

enter image description here

Activate[x] // MatrixForm
